bug#41791: [Shepherd] loses track of Tor

[Attila Lendvai]

i'm not sure this is related, but it's certainly a bug in MAKE-KILL-DESTRUCTOR
that it doesn't wait for the process to quit after sending it a signal, and thus
may restart the service while the previous instance is still running.

it's also not sending it a kill -9 after a timeout if the process is not
responsive.
