I am indeed working towards this. Believe it or not PerlIO in the 5.7.*
branch is heading this way.

The problem is that on Win32 to use select() the Socket has to be in
synchronous mode. While to use WaitForMultipleEvents() the Socket has
to be in asynchronous mode - thus if you want to use Win32's native "poll-oid"
API you _cannot_ use select(). In addition MS's C runtime (read/fread etc)
will not work on sockets in asynchronous mode (or non-blocking IO in general).
So you need to replace read and stdio with another IO subsystem and get
perl to use it - hence PerlIO.
Or you use stdio/read and select() in which case _ONLY_ sockets will work
(and apparently not listen mode sockets at that...)
So I _strongly_ recommend the PerlIO route - but please copy me
whatever way you go.
