No, when STAT is marked "R", it just means that the process is on the
ready-to-run queue in the process scheduler. Also keep in mind that top or
ps may be task-switched between retrieving the info for one process and
the info for the next, depending on whether it's making multiple syscalls.
So what you see may not be a true, instantaneous process snapshot.

That's not a bug; that's a feature!
