Thus I expected to see ~20 mb swap usage).
I am seeing this with Mozilla in an Xnest session. Even after I terminate Mozilla + Xnest there is a huge amount of swapped-out memory (~100MB). This is on a system with 320MB of memory. Since the problem goes away when I leave X I had assumed it was an X bug (Fedora Core 1, not up-to-date) but now I wonder... Kernel version is 2.6.9 + patches from L-K but problem is the same in base 2.6.9.
