You probably first suspend a process? If a process was suspended by
swsusp then we can just ignore the restriction because it will be
returned later.

The admin wants the system to behave in a consistent way. If he suddenly
finds a process running on a cpu that was forbidden then that is weird
and surprising to say the least and may go undetected for a long time.
If the process gets killed when he disables the cpu then he will have to
fix up his cpu restrictions.
