With the attached patch, I am trying to measure maximum intra-CPU stime skew. This is not (necessarily) intended to be applied, but I'd be very interested in review to see if I am measuring it accurately or if there might be other more accurate methods than these three. I'd also be interested in measurements from other machines and configurations. (Output obtained with "xm debug-key t" which can be iterated in a shell loop to collect samples for one of the collection methods... they others are collected automatically.) If it is accurate, skew is worse than I had previously thought. Not horribly worse, but I am seeing 30-40us skew (on hpet) instead of the 11us I was seeing before.
