Oops -- hotkey-setup not quite fixed yet

Oh, no! Hotkey-setup locked my machine on boot again today :( It re-booted fine, though, which is progress over the previous settings where it locked up every time. Makes me think that the deadlock is with a service of the same priority as hotkey-setup (I have about 10), because there is no guarantee of the order in which they start even with RUN_PARALLEL set to "no". If this happens again, I am going to look into figuring out the dependency.
