3. It might be nice to do something like swap priorities. When I know
that task xyz is memory hog that traverses memory in linear way, you
may want system not to give it too much memory. Might be nice. (I have
it partly implemented - now I can set swap priority. But the way I did
it it gave 0% performance gain, so...)

What might be even nicer would be for system to look for memory access
paterns. Could do a _lot_ of difference, but also is really hard.
