I wouldn't expect it to be much of an improvement. That's why the 
priority is low. It's 'nice to have' feature but the amount of details 
that can go wrong vs. slight performance improvement it'll yield makes 
the value of the change dubious.

If you are interested in doing something low level there's ZMQ-204 for 
example. It's not necessarily a bug, but it's something we've never 
really tested. The question is: If one application connects to another 
one and sends RST before the connection is accepted, will it work ok? I 
would expect it to hang up. The listener socket is a blocking one, so 
accept will hang till another connect attempt occurs. If so, it can 
block whole I/O thread for an indefinite amount of time. It's very rare 
situation, but a nasty one.
