DATAGRAM POLL

Again totally generic. This also handles sequenced packet sockets providing the socket receive queue is only ever holding data ready to receive.  

NOTE

when you _don't_ use this routine for this protocol, and you use a different write policy from sock_writeable then please supply your own write_space callback.
