+%description
+The stalld program monitors the set of system threads,
+looking for threads that are ready-to-run but have not
+been given processor 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.
