Comment 7 for bug 1518935

<ted> So I think that the answer is, yeah, we do that syncronously.
 We do a dbus call to cgmanager to get the list of pids and try to write their proc value.
 If we fail, then we need a setuid helper for things like oxide.
 So it could be that spawning that helper is part of what is causing a delay
 I'm not sure how to do it another way though.
 We're not blocking on it running, the overhead is just starting it.
