yes, we already know. next time try to imagine _why_ nobody answered
your mail instead of reposting it almost 1:1.

to me this sounds like "what's the difference between a sparrow?".

anyway, just a few hints:
- setRunPrivileged applies only if the _parent_ is setuid root. however,
  that will never be the case if KApplication was already instantiated
  in that process.
- setPriority(<less than the current prio>) works only if the _parent_
  has root permissions; either by setuid or by inherited "native" root.
