It's ugly, but it works. There's a fundamental impedence mismatch
between glib and slirp/iohandler. Either you convert glib's pollfds to
fd_sets, or you take slirp and iohandler's fd_sets and put them in
pollfds. Converting slirp and iohandler to produce pollfds is not easy
because Windows does not have poll---so you'd still have a
pollfd-to-fd_set conversion somewhere. Believe me, I thought this
through. :)
