I've got a pesky process (in this case, a stranded process that was supposed to be running in iPhone Simulator (now long quit).
97442 ?? 0:00.00 (MyProcess)
I've tried everything I can think of, including
sudo kill -9 97442 sudo kill -HUP 97442
And yet, like the Raven... the process remains.
In this case, it means in order to continue working I have to reboot my machine.
