we weren't actually using these sources anymore, okay?

-//
-// This header file defines a `CycleClock`, which yields the value and frequency
-// of a cycle counter that increments at a rate that is approximately constant.
-//
-// NOTE:
-//
-// The cycle counter frequency is not necessarily related to the core clock
-// frequency and should not be treated as such. That is, `CycleClock` cycles are
-// not necessarily "CPU cycles" and code should not rely on that behavior, even
-// if experimentally observed.
-//
-// An arbitrary offset may have been added to the counter at power on.
-//
-// On some platforms, the rate and offset of the counter may differ
-// slightly when read from different CPUs of a multiprocessor. Usually,
-// we try to ensure that the operating system adjusts values periodically
-// so that values agree approximately.   If you need stronger guarantees,
-// consider using alternate interfaces.
-//
-// The CPU is not required to maintain the ordering of a cycle counter read
-// with respect to surrounding instructions.
