Picking a timer tick is a bit like picking the color of a window. Everybody has an opinion and there is no truly "right" choice. I guarantee you whatever you pick, someone will come along and say: why not X instead?
A power-of-2 value obviously makes it easy to divide by HZ.
Robert> More importantly, can we change to 1000?
On ia64, you can make it anything you want. User-level will pick up the current value from sysconf(_SC_CLK_TCK).
