Sorry for followup on my own mail, but there is another thing that
comes to my mind:
swap_out is currently in no way priority-dependant. But it could be
(the parameter is there). How about swapping more pages in tighter
memory situation? The basic idea is that if there is a rising need for
mem it cannot be wrong to do a bit more than under normal
circumstances. One could achieve this simply by:
int counter, nr_pages = SWAP_CLUSTER_MAX;
to
int counter, nr_pages = SWAP_CLUSTER_MAX * DEF_PRIORITY /
priority;
in swap_out.
The idea behind is to reduce the overhead in finding out if swapping
is needed by simply swapping more everytime we already gone "the long
way to knowing".

Stephan
