You can have a look at Circus - https://circus.readthedocs.org which is
a process manager.
"circusctl" is used to control "circusd" using ZeroMQ
The nice thing about zmq as opposed to signals is that you can code your
thing independantly from the transport
then choose which transport fits a situation: TPC (then the ctl can be
on another box), IPC or even ITC
That also means your ctl part can be portable to any platform
