A win32event based implementation of the Twisted main loop.
This requires pywin32 (formerly win32all) or ActivePython to be

Event loop handling of writes is *very* problematic (this is causing
failed tests). Switch to doing it the correct way, whatever that means
Replace icky socket loopback waker with event based waker (use
Switch everyone to using Free Software so we don't have to deal with
IIRC, sockets can only be registered once. So we switch to a structure
like the poll() reactor, thus allowing us to deal with write events in
a decent fashion. This should allow us to pass tests, but we're still
limited to 64 events.
Instead of doing a reactor, we make this an addon to the select
reactor. The WFMO event loop runs in a separate thread. This means no
need to maintain separate code for networking, 64 event limit doesn't
apply to sockets, we can run processes and other win32 stuff in default
event loop. The only problem is that we're stuck with the icky socket
based waker. Another benefit is that this could be extended to support
>64 events in a simpler manner than the previous solution.
The 2nd solution is probably what will get implemented.
