There's a (slightly outdated?) patch available on my home
page, though...

Cool. It will be interesting to see how this compares to my
OOM killer (and to the other approaches that will undoubtedly
surface over the next few months).

I'm definately looking forward to an "OOM killer showdown"
where we can compare how the different OOM tactics work.
Not because I think it matters all that much on most systems
(good admins put in enough memory&swap), but simply because
it appears there has been amazingly little research on this
subject and it's completely unknown which approach will work
"best" ... or even, what kind of behaviour is considered to
be best by the users...
