I have been wondering about the locking stuff for a while too. These
are probably dumb questions but my OS terminology is not what it could
be. (Is there a good reference somewhere?)

* Does "lock the kernel" mean "prevent anyone else from executing any
kernel code"?

* If so, what happens if some other CPU is already inside the kernel?
Is there some mechanism to stop the other CPU??

TIA
