No.  On 32 bit machines that would only result in 2**31 - 1 passes
through the loop, not quite a practical infinity.  On 64 bit machines,
2^63 - 1 would be a practical infinity.

The latest patch uses None instead, which doesn't fail when asyncore.py
exists.  The use of FP infinity was a cute hack, but only worthwhile if
you can rely on FP infinity being marshalled and unmarshalled correctly.
I didn't know there was an issue with such things, but should have
tested it on my end before posting it.  I have tested None, and at least
with Python 2.3, it works fine.
