No: I meant that a programmer's mistake is easy because you're basically
blocking a thread on another one. If for instance you send a similar
blocking queued signal from this thread to the former, you get a
deadlock (since the former is blocked waiting for the first signal to
finish its process).
My suggestion mostly is not to use blocking queue signals.
