+The starved program monitors the set of system threads, looking for threads
 that are ready-to-run but have not been given cpu time for some threshold period. When
 a starving thread is found, it is given a temporary boost using the SCHED_DEADLINE
 policy. The default is to allow 10 microseconds of runtime for 1 second of clock time.
