Ok, you _can_ gather statistics, and modify caps/nice on the fly... for
long running tasks.  How long does a task have to exist before you have
statistics for it so you can manage it?

Also, if you're going to need a separate resource manager to allocate,
monitor and modify in realtime, why not go whole hog, and allocate and
monitor instances of uml.  It'd be a heck of a lot easier.
