I don't quite understand that, unless you're meaning that FD_WRITE is
edge-triggered.
In that case, wouldn't it be possible to mark sockets that have
writability signaled 'writable' and using a zero-timeout select() call
to determine if those sockets are still writable just before invoking
the next wait?

A separate backend would be my preference as well.

What do you mean by 'the POSIX event model'?
