Not particularly, poll() would have to make the same assumption, but
honestly I don't think treating the null case as "everything" is
clean.  It's a hack.  Better to be 100% consistent.

However we have not found any valid use cases for blocking recv() on
dead SUB sockets.  The one Matt described specifically must side-step
the dead SUB socket if it's to work at all.

Meaning a "wtf?" assertion in such cases would be the sanest reaction from 0MQ.
