That process works in my mind but not in reality yet.

along with the other 2 dozen infrastructure projects... yeah, too lazy
:-)
Need to study more stuff on cgroups anyway. I really like the bit about
being able to limit resources by application to avoid a runaway process
eating a system. See comment about "time" above...
