Just note please that 2.4 and 2.6 kernels behave differently here.
2.4 kernel can wakeup only 50 times a second while 2.6 500 times,
I beleive.

In other words

while(1){
	/* do nothing */
	usleep(1);
	calculate_fps();
}

will (well, should ;) result in 50 FPS on 2.4 kernel.

Not sure if select() will work correctly, probably not.

To implement precise usleep() gettimeofday() should be used, imo.
