Well, you can't stop services without the appropriate permissions, so that leaves a large number of "processes" that are untouchable. I can think of at least one way to approximate that (for all non-service processes), but I have to ask why you want to do this. Most processes take very little CPU time, especially when they're not focused/active, so performance can't possibly be the issue.

a friend has requested it, who runs many apps, and "cannot afford to shutdown or leave some app running without monitoring it"

I would point out to your friend that if he pauses or freezes an app, he's not going to be monitoring it, or at least monitoring it won't really have any effect since it won't be doing anything while it's frozen. Sorry, but it sounds like a bogus reason to me.

You would need kernel privileges to do such operations yourself. But since these operations are already available in the OS you can simply use these.

Good luck!
