I'm investigating a patch from Norman Vine right now.  I will try to
submit it or a variation of it to the patch collector ASAP -- hopefully,
in time for beta 2.

Cygwin Python with threads seems to work for others too (without hangs).
Unfortunately (or fortunately depending on your perspective), it hangs
fairly often on my main Windows machine.

The only explanation that I can come up with is that you are using a
snapshot that has the poll fix but not the strftime one.  If you are still
using the stock 1.3.3, then I'm at a loss to explain your observations.

Just like on Unix:

    $ uname -a
    CYGWIN_NT-5.0 ALTHEA 1.3.4(0.46/3/2) 2001-10-26 21:17 i686 unknown

Thanks,
