-// Originally, this USER_HZ value was dynamically retrieved via a sysconf call
-// which required cgo. However, that caused a lot of problems regarding
-// cross-compilation. Alternatives such as running a binary to determine the
-// value, or trying to derive it in some other way were all problematic. After
-// much research it was determined that USER_HZ is actually hardcoded to 100 on
-// all Go-supported platforms as of the time of this writing. This is why we
-// decided to hardcode it here as well. It is not impossible that there could
-// be systems with exceptions, but they should be very exotic edge cases, and
-// in that case, the worst outcome will be two misreported metrics.
