Or actually, it may be less work to just actually spawn kernel
threads... it's probably less work than I've been thinking it is. afsd
just exits if the daemon pioctls return anyway, so we could just have
them spawn a kernel proc and then return. We'd lose any per-process
priority goo that afsd sets for the proc, but I don't think we do any of
that on Solaris anyway.

It's still incredibly annoying, though. And it doesn't seem good to
change something like that in the middle of a stable series.
