8f07b1a417 [mem/task] Fix broken handling of page faults
The method I was using resulted in a loop of halts attempting
to remove process 0 from the thread queue if the kernel itself
was doing the faulting. This should fix that. Once there are
no more processes available, we bail out and call STOP.

202d5af168 Fix broken task switching. [...]
We failed to inform the compiler of which registers we were clobbering
in performing that bit of assembly, so it did a wonderfully fun thing
and move esp into %ecx, eip into something, that something into %ecx,
then tried to load %ecx into %esp. Oops. *boom*.
