      Mutex profiles now scale contention by the number of goroutines blocked on the mutex.
      This provides a more accurate representation of the degree to which a mutex is a bottleneck in
      a Go program.
      For instance, if 100 goroutines are blocked on a mutex for 10 milliseconds, a mutex profile will
      now record 1 second of delay instead of 10 milliseconds of delay.
