You could do something like this, which we invoke from /etc/rc.local

#!/bin/sh
#kpatch: apply local patches to the running kernel
#	set max per-user processes to 200

N=/vmunix
D=/dev/mem

adb -w -k $N $D <<\EOF
maxuprc/W 0t200
$q
EOF

#!/end

If you have a dump, looking at the process table with ``ps'' should
show hundreds of copies of the shell script running.
