Yes, and you could use whatever algorythm you like to get the job done --
wouldn't be hard to make it really flexable.. like a list of processess
that should never be killed, a list that should be killed first, and an
algorythm for selecting processes not mentioned in the list. I don't know
why all these people are debating it on the kernel list. If you need such
a thing.. go code it (and make it configurable while your at it.) :)
