The UI's been feeling pretty "laggy" for a while so I thought I'd
revisit this thread.
Here's the output of "intrstat 5". Steady state is around the 20000
mark, and dragging a big Thunderbird window around (causing a lot of
gnome-terminal windows to white out and not redraw themselves
immediately) increases it to around 24000.
bash-3.2$ pfexec intrstat 5
