Probably write off as buggy. Some automated way to detect that it's buggy might be nice though... > Here's another question that I have after reading up on this stuff.

Some programs call gettimeofday() a *lot*, and there's quite a difference in performance between the various clock sources. On my laptop, timing a loop of 5,000,000 gettimeofday() calls: acpihpet: 0m3.29s acpitimer: 0m10.49s i8254: 0m21.44s (I wonder how an ITSC-based timecounter would look...)
