You see, sometimes, once in a great while, I get panics when doing
development and I don't necessarily have three machines around. As a
good developer, I'd like to track them down, but your advice
apparently is that I should run Solaris or NT instead.

But somehow, that does happen to me a lot. I suppose I should stop
performing stunts like helping to port drivers while at IETF meetings.

I also have a PC that has trouble during boot, for which DDB is the
only tool I can use because I can't force a core dump.
