* This maps directly to the "nice" priorities we use in Android.
|

||||||
* 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.
