Everything should now work again.
See the comments for the .h files mass checkin (e.g. pystate.h) for
more detail.

Py_Initmodule(), which is a macro wrapper around it).
The return value is now a NULL pointer if the initialization failed.
This may make old modules fail with a SEGFAULT, since they don't
expect this kind of failure. That's OK, since (a) it "never" happens,
and (b) they would fail with a fatal error otherwise, anyway.
Tons of extension modules should now check the return value of
Py_Initmodule*() -- that's on my TODO list.

Introduce truly separate (sub)interpreter objects. For now, these
must be used by separate threads, created from C. See Demo/pysvr for
an example of how to use this. This also rationalizes Python's
initialization and finalization behavior:
Py_Initialize() -- initialize the whole interpreter
Py_Finalize() -- finalize the whole interpreter
tstate = Py_NewInterpreter() -- create a new (sub)interpreter
Py_EndInterpreter(tstate) -- delete a new (sub)interpreter
There are also new interfaces relating to threads and the interpreter
lock, which can be used to create new threads, and sometimes have to
be used to manipulate the interpreter lock when creating or deleting
sub-interpreters. These are only defined when WITH_THREAD is defined:
PyEval_AcquireLock() -- acquire the interpreter lock
PyEval_ReleaseLock() -- release the interpreter lock
PyEval_AcquireThread(tstate) -- acquire the lock and make the thread current
PyEval_ReleaseThread(tstate) -- release the lock and make NULL current
Other administrative changes:
- The header file bltinmodule.h is deleted.
- The init functions for Import, Sys and Builtin are now internal and
declared in pythonrun.h.
- Py_Setup() and Py_Cleanup() are no longer declared.
- The interpreter state and thread state structures are now linked
together in a chain (the chain of interpreters is a static variable
in pythonrun.c).
- Some members of the interpreter and thread structures have new,
shorter, more consistent, names.
- Added declarations for _PyImport_{Find,Fixup}Extension() to import.h.

Even less shuffling of stdout (only at start of new interpreter).
Interact properly with new interpreter initialization conventions
(must use Py_Initialize/Py_Finalize *and*
Py_NewInterpreter/Py_EndInterpreter).
Probably more minor changes.

while one thread is blocked in mainloop(). Also, handle signals (not
just interrupts) as soon as they happen.
Cleanup: remove support for Tcl/Tk versions 7.4/4.0. (I've confirmed
that it works for 7.5/4.1 and 7.6/4.2, as well as 8.0b2.)
Coding style change: instead of ``func (args)'', write ``func(args)''
everywhere.
Minor functionality change: use PyArg_ParseTuple everywhere. This
should only affect the errors reported for bad argument lists; in
particular, deletefilehandler() is much clearer about what's going
on.
(XXX Still to do: Mac and Win ports to 8.0b2.)

the comma after the day name is optional if it is a recognized day
name; and the date and month may be swapped. Thus, the following two
test dates will now be parsed correctly:

Thu Feb 13 12:16:57 1992

Re-sequenced the function descriptions so that the formatting is described
before the assumption is made that the reader has a clue about the formatting.
Moved examples to be closer to the functions being demonstrated.
Added example of saferepr() result.

but we don't want to use it.
