Well it follows the "nice" semantic, the the documentation of the nice
system call:
nice() adds inc to the nice value for the calling process. (A
higher nice value means a low priority.) Only the superuser may specify
a negative increment, or priority increase. The range
for nice values is described in getpriority(2).
Of course the nice limit is more fine grained these days. IIRC it was a
soft resource limit now the last time I looked.
We would essentially need something similar for the GPU if we want to
allow a regular process to get a higher priority.
