Totally agreed.

We did start a 'futzing' issue to make 0MQ robust against random data,
with a simple tool I made to send random data to 0MQ ports. That
already caught one or two problems.

it's only when there's an assert that people need IMO any information
that will help them accurately report and/or solve the problem.

If we decide 0MQ should not 'guess' at habitual application errors,
that's fine by me. We do in that case need a better knowledge base of
asserts and what they could mean. Maybe a wiki page...?
