  Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
  (SIGINT). If an error occurs while importing the site module, the error is
  printed and Python exits. Initialize the GIL before importing the site
  module.

  Fix issue #1590864, multiple threads and fork() can cause deadlocks, by
  acquiring the import lock around fork() calls. This prevents other threads
  from having that lock while the fork happens, and is the recommended way of
  dealing with such issues. There are two other locks we care about, the GIL
  and the Thread Local Storage lock. The GIL is obviously held when calling
  Python functions like os.fork(), and the TLS lock is explicitly reallocated
  instead, while also deleting now-orphaned TLS data.

  This only fixes calls to os.fork(), not extension modules or embedding
  programs calling C's fork() directly. Solving that requires a new set of API
  functions, and possibly a rewrite of the Python/thread_*.c mess. Add a
  warning explaining the problem to the documentation in the mean time.

  This also changes behaviour a little on AIX. Before, AIX (but only AIX) was
  getting the import lock reallocated, seemingly to avoid this very same
  problem. This is not the right approach, because the import lock is a
  re-entrant one, and reallocating would do the wrong thing when forking while
  holding the import lock.

  Will backport to 2.6, minus the tiny AIX behaviour change.

Neal Norwitz dac090d3e6 Bug #1520864 (again): unpacking singleton tuples in list comprehensions and

Sigh, I only fixed for loops the first time, not list comps and genexprs too.
I couldn't find any more unpacking cases where there is a similar bug lurking.

This code should be refactored to eliminate the duplication.  I'm sure
the listcomp/genexpr code can be refactored.  I'm not sure if the for loop
can re-use any of the same code though.

Will backport to 2.5 (the only place it matters).

that use pdb or tracing could test heavily.
