PEP 285.  Everything described in the PEP is here, and there is even
some documentation.  I had to fix 12 unit tests; all but one of these
were printing Boolean outcomes that changed from 0/1 to False/True.
(The exception is test_unicode.py, which did a type(x) == type(y)
style comparison.  I could've fixed that with a single line using
issubtype(x, type(y)), but instead chose to be explicit about those
places where a bool is expected.

Still to do: perhaps more documentation; change standard library
modules to return False/True from predicates.

code (if it isn't open already).

PythonIDE still opens the resource file "manually" because it also uses
presence of the CURS resource to determine whether it needs to adjust
sys.path.

PyArg_ParseTuple() as part of the format string.

 457466: popenx() argument mangling hangs python
 226766: popen('python -c"...."') tends to hang

Fixes argument quoting in w9xpopen.exe for Windows 9x.  w9xpopen.exe
also never attempts to display a MessageBox when not executed
interactively.

Added test_popen() test.  This test currently just executes
"python -c ..." as a child process, and checks that the expected
arguments were all recieved correctly by the child process.  This
test succeeds for me on Win9x, win2k and Linux, and I hope it does
for other popen supported platforms too :)

Please review.

How do I create a cross reference to section 4.1?

Replace section 4.1 with section A.3.

The new section 4.1 is titled "Naming and binding."  It includes the
text of section A.3 augmented with some of the detailed text from the
old section 4.1.

The \dfn, \index stuff is probably wrong, but I tried.

Also update other parts of appendix A to mention that nested scopes
and generators are standard features.

possible pool states.  I think it's much clearer now.

Added a new long overdue block-management overview comment block.

I believe the comments are in good shape now.

Added two comments about possible small optimizations (one getting rid
of runtime multiplications at the cost of a new pool_header member; the
other getting rid of runtime divisions and the pool_header capacity
member, at the cost of a static const vector of 32 uints).
