test_math and test_cmath are failing on the FreeBSD 6.2 trunk buildbot,
apparently because tanh(-0.) loses the sign of zero on that platform.
If true, this is a bug in FreeBSD.
Added a configure test to verify this. I still need to figure out
how best to deal with this failure.

This should fix issue2632. A long description of the two competing
problems is in the bug report (one old, one recently introduced trying
to fix the old one). In short:
buffer data during socket._fileobject.read() and readlines() within a
cStringIO object instead of a [] of str()s returned from the recv()
call.
This prevents excessive memory use due to the size parameter being
passed to recv() being grossly larger than the actual size of the data
returned *and* prevents excessive cpu usage due to looping in python
calling recv() with a very tiny size value if min() is used as the
previous memory-use bug "fix" did.
It also documents what the socket._fileobject._rbufsize member is
actually used for.
This is a candidate for back porting to 2.5.

In test_io, StatefulIncrementalDecoderTest was not part of the test suite.
And of course, the test failed:
a bytearray was used without reason in io.TextIOWrapper.tell().
The difference is that iterating over bytes (i.e. str in python2.6) returns 1-char bytes,
whereas bytearrays yield integers.
This code should still work with python3.0
