A very naive select/poll busy-poll support. Add busy-polling to sock_poll(). When poll/select have nothing to report, call the low-level sock_poll() again until we are out of time or we find something. Right now we poll every socket once, this is suboptimal but improves latency when the number of sockets polled is not large.

I am a bit uneasy with this one, because an applicatio polling() on one thousand file descriptors using select()/poll(), will call sk_poll_ll() one thousand times. ------------------------------------------------------------------------------ How ServiceNow helps IT people transform IT departments: 1.
