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).

Fix two typos spotted by Joonas Paalasmaa

Split the description of co_flags into two paragraphs.  The first
describes the flags that are used for non-future purposes, where
CO_GENERATOR was added.  The second describes __future__'s use of
co_flags and mentions the only one currently meaningful,
CO_FUTURE_DIVISION.

func_closure is a readonly attribute.
Add \ttindex{} for func_closure.
Remove discussion of func_closure specific to 2.1.

directly.

Convert to use PyModule_*() instead of manipulating the module dict directly.

This displays stats about the # of arenas, pools, blocks and bytes, to
stderr, both used and reserved but unused.

CAUTION:  Because PYMALLOC_DEBUG is on, the debug malloc routine adds
16 bytes to each request.  This makes each block appear two size classes
higher than it would be if PYMALLOC_DEBUG weren't on.

So far, playing with this confirms the obvious:  there's a lot of activity
in the "small dict" size class, but nothing in the core makes any use of
the 8-byte or 16-byte classes.

directly.

Fix floating point exception if mpz.powm(10, 1, 0) (modulus == 0).
Add a test.

I left the email pkg alone; I'm not sure how Barry would like to handle
that.

Add test for file.readinto().

I really can't test this, but from reading the discussion in that bug
report, it's likely that this works.  It may also close a whole bunch
of other bug reports related to urllib and proxies on Windows, but who
knows.

in OSX MacPython (untested), and should be disabled/removed in OS9 (but
that doesn't happen yet).

Use METH_OLDARGS explicitly rather than implicitly.

Please review for correctness.

  Convert METH_OLDARGS -> METH_VARARGS: also PyArg_Parse -> PyArg_ParseTuple
  Convert METH_OLDARGS -> METH_NOARGS: remove args parameter
Please review.  All tests pass, but some modules don't have tests.
I spot checked various functions to try to make sure nothing broke.

These should be safe.
