*chuckle*  Uh, actually, as things are right now, malloc(... M_WAIT)
_cannot_ return NULL.  Not "it's defined to not," it will never do so
with the current implementation.

re: fixing the kmem_malloc() panic: well, i'm working on that.  That's
what got me to asking these questions.  (I noticed what code was doing
with MGET, etc., even though it was unrelated, and it made my
uncomfortable. 8-)
