Well, when I first wrote the code a long time ago, I thought
that smp_send_stop() would be sufficient to lock down all the
rest of the processors, but I didn't take care of the processor
that was doing the dumping.  You are correct, however -- this
is a problem and I have to fix it."Matt D. Robinson" wrote:

get my !)(@*$%(#)*^! CVS repository opened back up -- that's
what I get for changing my domain name again).
