Without setting any options on the sockets, messages will normally get
load balanced from PUSH to PULL sockets, and indeed the sender will
queue outgoing messages until it can deliver them.  If you have a
minimal case where this does not happen, post it.  Note that if you're
using 0MQ/2.0.x you must wait in the sender until all messages are
sent.  If you kill either program before all messages have been sent,
they may be lost.
