Add internal routine _PyModule_Clear(), which does approximately what
...
clear_carefully() used to do in import.c. Differences: leave only
__builtins__ alone in the 2nd pass; and don't clear the dictionary (on
the theory that as long as there are references left to the
dictionary, those might be destructors that might expect __builtins__
to be alive when they run; and __builtins__ can't normally be part of
a cycle).

Add a new function PyNumber_CoerceEx() which works just like
...
PyNumber_Coerce() except that when the coercion can't be done and no
other exceptions happen, it returns 1 instead of raising an
exception.
Use this function in PyObject_Compare() to avoid raising an exception
simply because two objects with numeric behavior can't be coerced to a
common type; instead, proceed with the non-numeric default comparison.
Note that this is a somewhat questionable practice -- comparisons for
numeric objects shouldn't default to random behavior like this, but it
is required for backward compatibility. (Case in point, it broke
comparison of kjDict objects to integers in Aaron Watters' kjbuckets
extension.) A correct fix (for python 2.0) should involve a different
definiton of comparison altogether.

Fix problem discovered by Barry: if you hit ^C to

dict_get(): New method for item access with different semantics than

Allow assignments to instance.__dict__ and instance.__class__. The

former lets you give an instance a set of new instance vars. The
latter lets you give it a new class. Both are typechecked and

For classes, the check for read-only special attributes is tightened
so that only assignments to __dict__, __bases__, __name__,
__getattr__, __setattr__, and __delattr__ (these could be made to work
as well, but I don't know if that's useful -- let's see first whether
mucking with instances will help).

Change the Fini function to only remove otherwise unreferenced strings

from the interned table. There are references in hard-to-find static
variables all over the interpreter, and it's not worth trying to get

subtle failures later -- so we have to keep them in the interned

Add optional 'sizehint' argument to readlines(). After approximately

this many bytes have been read, readlines stops. Because of

f3e85a0356
Changes that appear to give another 12% speedup.
...
Rather than allocating a list object for the fast locals and another
(extensible one) for the value stack and allocating the block stack
dynamically, allocate the block stack with a fixed size (CO_MAXBLOCKS
from compile.h), and stick the locals and value stack at the end of
the object (this is now possible since the stack size is known
beforehand). Get rid of the owner field and the nvalues argument --
it is available in the code object, like nlocals.
This requires small changes in ceval.c only.
