Vladimir Marangozov's long-awaited malloc restructuring. 

For more comments, read the patches@python.org archives.
For documentation read the comments in mymalloc.h and objimpl.h.

(This is not exactly what Vladimir posted to the patches list; I've
made a few changes, and Vladimir sent me a fix in private email for a
problem that only occurs in debug mode.  I'm also holding back on his
change to main.c, which seems unnecessary to me.)

Each interface exports both functions and macros. Extension modules
should normally use the functions for ensuring binary compatibility
of the user's code across Python versions. Subsequently, if the
Python runtime switches to its own malloc (different from standard
malloc), no recompilation is required for the extensions.
The macro versions trade compatibility for speed. They can be used
whenever there is a performance problem, but their use implies
recompilation of the code for each new Python release. The Python
core uses the macros because it *is* compiled on every upgrade.
This might not be the case with 3rd party extensions in a custom

source of 3rd party deliverables). You have been warned! */

Additional macros for modules that implement new object types.
Functions and macros for modules that implement new object types.
You must first include "object.h".
PyObject_NEW(type, typeobj) allocates memory for a new object of the given
type; here 'type' must be the C structure type used to represent the
object and 'typeobj' the address of the corresponding type object.
Reference count and type pointer are filled in; the rest of the bytes of
the object are *undefined*! The resulting expression type is 'type *'.
The size of the object is actually determined by the tp_basicsize field
of the type object.
- PyObject_New(type, typeobj) allocates memory for a new object of
the given type; here 'type' must be the C structure type used to
represent the object and 'typeobj' the address of the corresponding
type object. Reference count and type pointer are filled in; the
rest of the bytes of the object are *undefined*! The resulting
expression type is 'type *'. The size of the object is actually
determined by the tp_basicsize field of the type object.
PyObject_NEW_VAR(type, typeobj, n) is similar but allocates a variable-size
object with n extra items. The size is computed as tp_basicsize plus
n * tp_itemsize. This fills in the ob_size field as well.
*/
- PyObject_NewVar(type, typeobj, n) is similar but allocates a
variable-size object with n extra items. The size is computed as
tp_basicsize plus n * tp_itemsize. This fills in the ob_size field
as well.
#ifndef MS_COREDLL
- PyObject_Del(op) releases the memory allocated for an object.
- PyObject_Init(op, typeobj) and PyObject_InitVar(op, typeobj, n) are
similar to PyObject_{New, NewVar} except that they don't allocate
the memory needed for an object. Instead of the 'type' parameter,
they accept the pointer of a new object (allocated by an arbitrary
allocator) and initialize its object header fields.
Note that objects created with PyObject_{New, NewVar} are allocated
within the Python heap by an object allocator, the latter being
implemented (by default) on top of the Python raw memory
allocator. This ensures that Python keeps control on the user's
objects regarding their memory management; for instance, they may be
subject to automatic garbage collection.
In case a specific form of memory management is needed, implying that
the objects would not reside in the Python heap (for example standard
malloc heap(s) are mandatory, use of shared memory, C++ local storage
or operator new), you must first allocate the object with your custom
allocator, then pass its pointer to PyObject_{Init, InitVar} for
filling in its Python-specific fields: reference count, type pointer,
possibly others. You should be aware that Python has very limited
control over these objects because they don't cooperate with the
Python memory manager. Such objects may not be eligible for automatic
garbage collection and you have to make sure that they are released
accordingly whenever their destructor gets called (cf. the specific
form of memory management you're using).
Unless you have specific memory management requirements, it is
recommended to use PyObject_{New, NewVar, Del}. */
/*
* Core object memory allocator
* ============================
*/
/* The purpose of the object allocator is to make make the distinction
between "object memory" and the rest within the Python heap.
Object memory is the one allocated by PyObject_{New, NewVar}, i.e.
the one that holds the object's representation defined by its C
type structure, *excluding* any object-specific memory buffers that
might be referenced by the structure (for type structures that have
pointer fields). By default, the object memory allocator is
implemented on top of the raw memory allocator.
The PyCore_* macros can be defined to make the interpreter use a
custom object memory allocator. They are reserved for internal
memory management purposes exclusively. Both the core and extension
modules should use the PyObject_* API. */
