I have something which should work. I think Rik has been hiding the
problem and I just noticed that I accepted into 99 a patch that definitely
should _not_ go in (the thing to change the "state" variable whether a
free operation works or not is wrong - we want to keep freeing from one
pool as long as it is "easy".
Rik, if you have problems with this under certain circumstances (like
swapping out too much even though there is plenty of buffers left), that
indicates that something is being too aggressive even though "i" (the
"aggressivemess factor") is set to a high value ("i = 6" means that it
shouldn't try all that hard, while "i = 0" means that we're really close
to meltdown and we should go crazy).
