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.
