Second, the timer channel associated with a `Timer` or `Ticker` is
now unbuffered, with capacity 0.
The main effect of this change is that Go now guarantees
that for any call to a `Reset` or `Stop` method, no stale values
prepared before that call will be sent or received after the call.
Earlier versions of Go used channels with a one-element buffer,
making it difficult to use `Reset` and `Stop` correctly.

      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.
