Does this mean that a lower priority task could do a sort of DOS attack
on a high priority task, if it creates a bunch of threads that
constantly grabs a shared lock from the higher priority task? That is,
the higher priority task could possibly lose a lot of its quota due to
other tasks running on its behalf in the critical section?
