kernel killing processes when out of swap

That makes sense. Me trying to connect to see what was going
on would hence cause sshd to be killed ( not good ).
It would seem that we could do with doing something to prevent this.
We have had a few suggestions so far.
1. Using madvise, requires code changes per app
2. Using a sysctl to name processes which shouldn't be killed.
3. Changing how the choice of process to kill is made.

I don't like the idea of having to make code changes so would
vote against #1. #3 I would imagine could be quite complex
and error fraught so #2 seems like the best option so far.

What do others think? Go with Marc's idea?
