Right now, I just changed team from the Online group to the Framework
group, so my work on ZMQ is currently limit to my free time and,
altough I had time to implement the collector pattern using the same
model as the one I wrote in Python, I'm not satisfy with its
scalability: it's too easy to either lost request or that a single
node block an entire sub-cluster.  I'm looking for some way to allow
requests to be queued at the edges without adding too much useless
latency to the protocol. My impression right now is either I don't
have a clear enough model for the pattern, or that I'm taking in the
wrong way (meaning I don't have the right model at all).
