In that case you'd have to implement poll/select (and kevent) with the help of fork(). It would be a much more heavyweight operation, especially since it causes another rump kernel handshake to happen. Furthermore, you cannot cache the workers. Well, maybe with __clone(CLONE_FILES), but ... So, yes, it would be possible, but not a good move since it doesn't solve any problems (apart from working around this kernel bug) and causes extra penalties. -- älä karot toivorikkauttas, kyl rätei ja lumpui piisaa
