alling mq_timedreceived with immediate timeout was getting stuck and not
...
timeout. Immediate timeout is achieved by setting absolute timeout value to
past time, for example abstime={ .tv_sec=0, .tv_nsec=0 }. However absolute
time was converted to relative time using unsigned integer arithmetic and
resulted large ticks count by clock_abstime2ticks, instead of expected negative
ticks value.
Patch corrects clock_abstime2ticks to return negative ticks, if absolute time
is in the past.

Add logic for priority inheritance with multiple worker threads. How should this work? Tentatively, the all get reprioritized together. It would be best to just reprioritize the single thread doing the high priority work, but we don't know which that will be in advance
