Even though using nginx on Windows goes way over my head (even for
development) and/or seing WIndows as any kind of server, I read that
Windows Vista+ support the poll (well, actually WSAPoll
<https://msdn.microsoft.com/en-us/library/windows/desktop/ms741669.aspx>)
system call.
Since XP may now reasonably be called something of the past, would not it
be nice to go for it? No epoll, though.
