* A thread priority should be chosen inverse-proportionally to
* the amount of work the thread is expected to do. The more work
* a thread will do, the less favorable priority it should get so that
* it doesn't starve the system. Threads not behaving properly might
* be "punished" by the kernel.
* Use the levels below when appropriate. Intermediate values are
* acceptable, preferably use the {MORE|LESS}_FAVORABLE constants below.
