-// CycleClock
-// A CycleClock tells you the current time in Cycles. The "time"
-// is actually time since power-on. This is like time() but doesn't
-// involve a system call and is much more precise.
-//
-// NOTE: Not all cpu/platform/kernel combinations guarantee that this
-// clock increments at a constant rate or is synchronized across all logical
-// cpus in a system.
-//
-// Also, in some out of order CPU implementations, the CycleClock is not
-// serializing. So if you're trying to count at cycles granularity, your
-// data might be inaccurate due to out of order instruction execution.
