Ok, after an hour still no panics.  Should it really be exiting on its
own this often, though?

$ lastcomm ksetest | cut -c1-20 | sort | uniq -c

  75 ksetest          -
 366 ksetest          -X

The above proceses were generated by the following loops in two
different vtys:

while sleep 10 ; do killall -9 ksetest ; done
while : ; do ./ksetest; done
