How would you define these precisely enough that a program could recognize
them?  When I manually kill such processes, I use a number of heuristics.
For instance, a GNU emacs or Korn shell process running hard but with very
small resident set size is probably in a loop due to losing its tty.  Last
night I killed a uuxqt process that had been running for four hours, using
about 12% CPU/real time on a Sun-3/280 (it might have been doing useful
stuff, but the system was having performance problems and I doubted it was
important enough).
