Out of curiosity I tried using psyco on this script, and inheriting
the frag class from psyco.classes.psyobj and using psyco.bind(main)
seemed to provide a substantial speedup (I haven't measured it exactly
because the application is input driven). 

To give an impression of the speedup I can say that without psyco
optimizing the frame slows steadily until about 10 frames per second
when I click the mouse as fast as I can, and in a position fairly high
and in the middle of the screen (where there is bound to be most frags
on the screen). With psyco I can push fairly fast on the mouse button
without leaving frame rate sync, and while pushing as fast as I
possible can on the mouse, the frame rate doesn't go lower than about
37 fps. Impressive in my eyes.
