It "works" in Windows 2000.  I've got a variant of a prototype (and
abandoned) Twisted Reactor that uses WaitForMultipleObjects for an
alternate asyncore.poll() implementation on Windows.  It sucks up 100%
processor when sending trivial amounts of data from a single socket (where
asyncore uses about 2%), but you do get the data.
