would be quite huge refactoring (minor in terms of functinality, but huge in
numer of lines of code), which whould take a time and would be hard to merge
afterwards.

Something realistic I can try to hack is:
1. turn off disconnecting on OOM (so that new connection would not crash
application)
2. fix everything about sending/receiving messages
3. setup a two zmq_streamer-like devices (old code and new code) opened to
the exernal world, so that anybody can test, set small ulimit -a for both
4. setup a slow consumer which also shows statistics from both devices

Will having this example working convince you?
