Adds a single function to improve generated bytecode.  Has a single line
attachment point, so it is completely de-coupled from both the compiler
and ceval.c.

Makes three simple transforms that do not require a basic block analysis
or re-ordering of code.  Gives improved timings on pystone, pybench,
and any code using either "while 1" or "x,y=y,x".

    Make sure we aren't masking any errors raised in tempfile.mkdtemp() by
    referencing the (then) unbound local 'dir'.

generalize to take a callback function and a void * data argument.
This might come in handy later... :-)

in normal cases, and also in error cases.

the foreground.

Arranged that all the objects exposed by __builtin__ appear in the list
of all objects.  I basically peed away two days tracking down a mystery
leak in sys.gettotalrefcount() in a ZODB app (== tons of code), because
the object leaking the references didn't appear in the sys.getobjects(0)
list.  The object happened to be False.  Now False is in the list, along
with other popular & previously missing leak candidates (like None).
Alas, we still don't have a choke point covering *all* Python objects,
so the list of all objects may still be incomplete.

Bugfix candidate.

_Py_AddToAllObjects() that simply inserts an object at the front of
the doubly-linked list of all objects.  Changed PyType_Ready() (the
 closest thing we've got to a choke point for type objects) to call
that.

a doubly-linked list, exposed by sys.getobjects().  Unfortunately, it's not
really all live objects, and it seems my fate to bump into programs where
sys.gettotalrefcount() keeps going up but where the reference leaks aren't
accounted for by anything in the list of all objects.

This patch helps a little:  if COUNT_ALLOCS is also defined, from now on
type objects will also appear in this list, provided at least one object
of a type has been allocated.

1. Move subprocess socket handling to a subthread - "SockThread".
2. In the subprocess, implement a queue and global completion and exit
flags.  Execute code after it is passed through the queue.  (Currently,
user code is executed in SockThread.  The next phase of development will
move the tail of the queue to MainThread.)
3. Implement an RPC message used to shut down the execution server.
4. Improve normal and exception subprocess exits.

(At this checkin a "pass loop" interrupt doesn't work on any platform.  It
will be restored for all platforms once user code execution is moved to
MainThread.)

which allows the file to compile and removes a warning about _XOPEN_SOURCE
being redefined (works on AIX 4.3 and 5.1 at least).
