The issue is that if signalStop is not-blocking, then we will interrupt the thread leading to the task being not stopped gracefully.

I think we will need something more advanced like a way to wait "for a certain amount of time" for the thread to stop then killing it.

@loicmathieu, Now, part of the worker shutdown process we await for the realtime triggers to complete stopping before interrupting them with Thread.interrupt in last resort. The configured termination grace period is a used as the max timeout for waiting for realtime triggers.

I like where it goes ;)

I wonder if the other Thread may be refactor to do the same (or to provide the ability to do the same). Let's keep that in mind for later and merge this one asap.
