Amazing. On behalf of anyone who has to deal with the Windows side of
things - thank you.

Side note: various sources claim that WSApoll is broken and MS is
doing nothing to fix it. So this approach makes it a lot easier for
people to rework things. Be that on the Windows side or if the BSD
people are interested in using something like kqueue.

Thanks
