I hope that the next edition of Python supports select.poll on Vista, or at
least that someone writes a third-party module fo it. As much as I'd love to
do it myself, it's probably beyond me.. i've never used poll before nor
written a Python extension. also, i don't have Vista.
Thanks

If you use Twisted, then you can use I/O Completion Ports, which are even
better than WSAPoll, and your code will also work with KQueue on BSD or
EPoll on Linux without any changes. :)

The current docs describe the I/O Completion Ports reactor as
"extremely experimental".

Is that overly conservative or is it as bleeding edge as it sounds?

(IIRC there have been caveats like this on the Windows reactors for
a while)
