Lower the priority of all other threads, which would be equivalent to
running Squeak under nice(1), which generally works fine.

This doesn't work because in contemporary linux SCHED_OTHER threads are all of the same priority. One can neither raise nor lower their priority. nice changes a process's dynamic priority, not its static priority (see sched_setscheduler(2) and my footnote)
