ctl-alt-del, in general, is the "reboot" button for a PC.  Only works

Interesting.  I have been unable to type any text at all... Hmm.  At least,
not on anything in raw mode.  Didn't think to try switching consoles.

This is a Jan 15th kernel.  I'm gonna make a -current in the next 20 minutes
or so.

That's what I'm *suspicious* of, because I know that I've had hangs like this
in the distant past (and also on a BSD/OS box) when KMEMSIZE was tuned too
small - but I don't know how to tune it under UVM.

Me Too; not reproducible by doing the same things, but sometimes happens.

Yup, me too.  I'm sincerely hoping it's temporary and/or already fixed.
At this rate, if I don't get it fixed, by the end of the year my NetBSD
machine will have crashed as often as my Windows box did during the week of
vacation time I spent using it.  :)
