Normal priorities could be subdivisions of larger priority levels.


That could be about 195 levels total if we keep the same numbers.

Alternately, the standard priority levels could be spread accross
all 5 larger levels. That means 7 normal priority levels each.
The user level would hold standard priorities from -3 to 3,
the batch level is from 4 to 10, and idle-eater is 11 to 19.
