I'm aware of a few closed source usages of multiprocess. I also think 
current versions of collectd rely on secondary process (there's been a 
Telemetry API added to avoid that, but AFAIK the support for Telemetry 
is not upstream in collectd yet), and so do/would any dump-style 
applications - in fact, we ourselves include one such application in our 
codebase (pdump, proc-info, etc.).
