	OK... I'll take this momment to comment.  I uncommented the
line with 'DDB' 'DEBUG' and 'DIAGNOSTIC' on it.  Man did that ever
make a slow kernel!  Anyways... while it's possible that I'm working
on a heisen bug here, loading the heck out of the machine all weekend
did not uncover the hang.  Should I try it with only DDB?

	What do I do to drop into the debugger?

	What I think I'm chasing here is a interupt (or other) race
bug that has to do with some combination of disk/serial/load generated
by a uucp connected news machine.  I'm still trying to chase it.

Dave.
