Sorry Rik, there was a misunderstanding here. I would really like to
have this integration. But AFAICS this is a major task. shrink_mmap
relies on the pages to be in the page cache and the pagecache does not
handle shared anonymous pages.

Thus shm does it's own page handling and swap out mechanism. Since I
do not know enough about the page cache I will not do this before
2.5. If you think it can be easily done, feel free to do it yourself
or show me the way to go (But I will be on vacation the next two
weeks).
