-it seems that there are currently no tests that check the proper
-behavior of thread_set_priority() when called by a thread that is
-running under priority donation.  The proper behavior, I assume, is to
-temporarily drop the donation if the set priority is higher, and to
-reassume the donation should the thread subsequently set its own
-priority again to a level that's lower than a still active donation.
