That works if there is enough memory after the "bad" process has been killed. The question is, is it necessary? Many systems can live with processes performing a little bit poorly for some minutes and I wouldn't do it.
It's fine that "many systems" can. But there is no easy way when the user or system can't. Flushing back to RAM is slow - that's not controversial. So it would help if there was a way to do this in advance of the need for the programs where that matters.

The outage ain't resolved until things are back to operating normally.
If things aren't back to 100% healthy, could be I didn't truly find the root cause of the problem - in which case I'll probably be woken up again in 30 minutes when the problem comes back.
