Thanks again. Got an example I can copy?  I'm looking at the 1.5
branch sys/ic/i82365.c. pcic_delay() uses tsleep() with no locking
that I can see.  (the only use of locks is in the pcic_event_thread).
Or are the locks needed on -current, but not the release branch?

I think that came out backwards -- using delay() means the code has to
run in a single thread -- but I get the picture :-).
