Linux does preemptive swapping. AFAIK, you can't turn it off, and if you
could, you probably shouldn't.
It will swap out dormant parts of memory, just in case you start up something
big, like X, or Netscape, or Emacs. (he he)
Under, say, 128MB of RAM, this makes a lot of sense, but when you go to half
and gig and beyond, it becomes less useful.

The used counter counts shared pages wrongly.
Shared libraries (.so files) that are loaded only once for several programs,
get counted once per program using them.
This is a bug, and no, all your memory is not being eaten.
