Description

I have a Firefox problem caused by DragonFly and/or libthread_xu.
sched_get_priority_min(SCHED_OTHER) and
sched_get_priority_max(SCHED_OTHER) return values PRIO_MIN (-20) and
PRIO_MAX(20), both defined in sys/sys/resource.h.
When pthread_attr_setschedparam is called to set scheduling priority for
scheduling policy SCHED_OTHER, the priority value is checked if it is
within range by comparing it to THR_MIN_PRIORITY(0) and
THR_MAX_PRIORITY(31), both defined in
lib/libthread_xu/thread/thr_private.h. When a value in the range [-20;
-1] is used, pthread_attr_setschedparam returns an error code of
ENOTSUPP, which NSPR doesn't like. More precisely, when Firefox is
compiled with the 'debug' pkgsrc option, an assert fails, abort() is
called and a coredump written.
