Time Stamp Counters

While investigating a different issue, I found myself looking again at accurate timing with the rdtsc instruction
to read the processor's Time Stamp Counters. I last blogged about this when looking at the jitter caused by system calls to the linux kernel, and things have changed quite a lot. This post is the result of my trip around this particular block again.
