Hi Michael,

Right now POLL_BUSY_LOOP is only used internally to control busylooping,
as a signal between sock_poll() and do_poll().
Our original intention was to expose that to the users of epoll().
The work on epoll() support is not finished yet.

I think we should not document this until we finalize epoll() support.

Thanks,
Eliezer
