Code review: Processor can attempt processing all threads even when interrupted (#177)

[Mark Mentovai]

Ted-

I have a patch that allows the processor to press on with other
threads even after being interrupted while walking one thread's stack.
If other threads would cause interrupts, this lets us take care of
them with fewer processing passes.
