An experienced programmer coming to 0MQ is likely to attempt their own
debugging, so what do you mean by newbie?

+1 for Pieter's context config option. I think I agree having a
default HWM would be good, however, only if HWM events are easily
exposed.

As an aside, any idea of the 0MQ behaviour under flooding with no HWM
but sane kernel virtual memory settings (i.e.,
/proc/sys/vm/overcommit_memory=2)...?
