I?m not sure if it?s exactly what you are looking for, but if it gets you part of the way there, seems like it?s at least worth a look.  At the least, it should be able to give you some ideas on how to proceed if it?s not a good fit as-is.

But for some external reasons, I need to fork some zmq worker and I would like to manage this fork like zthread/zactor.  Let`s call it zfork, and I would like to exchange some thoughts before start developing it.

That basically means you want a zactor. The zactor then can fork the
process in turn and handle the heart-beating.
