If you invoke it with the -A flag, then it will go into a
sleep loop on panic (-A stands for abort, but that didn't
work very well on OS X).  You can then attach with gdb
and get a stack trace or look at what the other threads
are doing.

The cpu numbers don't really mean anything except
for whether they're 0 (runs user code) or non-zero
(runs kprocs).
