%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.
