It does not make sense to retry compaction when a fatal signal is pending.Well, it might make sense. Presumably it is beneficial to other tasks.
Apart from Vlastimil's point, if I hit ^C, I want the task to die, as soon as possible. I don't want it to do things which are beneficial to other tasks, I want my shell prompt back, not spending seconds trying to compact memory. Some other task can do that if _it_ needs large contiguous chunks.
