 Just my 2 EURO-ct on this. The VM in 2.4.x mainline is definitely
broken for a lot of loads, especially under high memory stress. This
needs to be adressed and fixed ASAP. An I think most people here agree.

 Now, the question is what is the correct fix. There is Andreas?s stuff,
which fixes some scenarios. There is Rick's stuff which fixes others.
There is even the small few liner patch to vmscan.c by M.v.Leuwen, which
fixes/reduces the swapout problem for *my* situation.

 But frankly speaking, I personally don't care which solution goes in,
but it should be done quick. Patching up mainline every time just to get
decent VM behaviour is unacceptable for serious use.
