Kernel: Unlock the Process when exit()ing

Browse Source 
If there are more threads in a process when exit()ing, we need to give
them a chance to unwind any kernel stacks. This means we have to unlock
the process lock before giving control to the scheduler.

Fixes #891 (together with all of the other "no more main thread" work.)
