memory problem
I wonder why so much memory is used and my machine keeps on swapping.
I don't have many applications: iceweasel, liferea, a few xterm's, and
some small background processes.
Here's an output of htop several minutes after quitting iceweasel (it's
still running to do some clean up, I suppose). Below, the processes are
sorted by MEM%, but none of them are taking more that 4% CPU time.

Once iceweasel has really quit, everything is back to normal:
