Bug Description
Binary package hint: at
Processes in queue "a" are run with niceness 2. There is no way to request a lower niceness like 0.
This matters because some power-management mechanisms leave the CPU at a lower frequency and don't speed it up for programs with with niceness > 0 that need more CPU.
This behaviour is intended in the source code. The relevant line is:
nice((tolower((int) queue) - 'a' + 1) * 2)

This seems to be intended behaviour in the code
