I guess I really should explain the background.I'm looking at using this in a raw PC BIOS environment, where the only *guaranteed* timer only has a 55 ms granularity. There are ways to get better resolution by going straight to the hardware, but PC hardware being what it is (utter crap) that's a risky thing for trying to make something that works on all platforms.
Hence the question. The good news it that CPU is generally plentiful. -hpa
