[zeromq-dev] Extremely strange PUB/SUB behavior

I made a reproducible case in C++ where if you have two subscribers: one
listening to "a" and "b" and another listening to "a" "b" and "c" if you
close the socket of the subscriber listening to "a" and "b" the other
subscriber loses a "b" message for one sequence. I can't seem to reproduce
it where it stops getting "b" messages altogether, though, which is what I
see in production.
