Of course I meant poll_event. Well I am a bit confused ... :-)

I am currently trying to split the sock_reselect functionality and
introduce a separate function that takes over the checking if the socket
has been kicked out of main the select loop.

I just need to figure out where exactly I need to call that function.
I am also not sure whether any combination of the FD_... and FD_WINE...
flags suffices to tell if the socket is in the select loop or not,
because of the many different situations that may affect these flags.

Even after working on this code for a few months now, I still find the
management of the socket state flags and various masks pretty confusing.
But I'm getting there.
