Oh yeah, and one more thing about loadplugin-run. I also modified the memory calculations to be a little more accurate and to take swap into account - it's much more reflective of actual memory state now.

In fact, as you run more and more applications, you can watch the memory indicator on loadplugin-run increase into the red, then immediately decrease as applications get the "Low Memory" message from DBUS (which I conclude means that they're cleaning up cached data in order to free up memory - very cool). This is distinct from linux's file system cache, which is really close enough to "free memory" that it is often considered such (as is the case with loadplugin [em]and[/em] loadplugin-run).
