I've always wondered why xmame idled so poorly, 'til I found this code and
patched it so:

+ usleep(100); /* sleep for 1/10000 of a second */
curr = uclock();
} while (curr - target < 0);
Now I can concurrently run centiped, gyruss, 1942, and mrdo, all on my KDE
desktop (with xfishtank: 12 fish, 60 bubbles; xneko; top) with each at
-frameskip 9 -nosound, on a 16-bit visual, and with 12% cpu idle
(k6/233mmx.) Or I can run 12 copies of MrDo. :) *smoothly*
This patch messes up autoframeskip (okay with no sound; seeks 7-9) but
works *beautifully* with manual frameskip + throttling.
I'm working on a better frameskip scenario that won't have this problem,
or the dropped-frames-when-sound-is-enabled-and-frameskip-exceeds-7 bug.
