If an innocent task was getting the trashing mem bit set it could decrease
interactive performance, I know. But how can it hurt stability?

It was the flushcount in vmscan.c or the free_before_allocate that can
have made differences. I think the vmscan.c changes are very right. The
free_before_allocate just avoids the machine to runs too near to the min
limit but it shouldn't be necessary and I'm going to drop it. If the
freepages.min limit was too low just increase it ;)
