Concurrent calls to time.Timer.Reset

[Duncan Harris]

Is it safe to make calls to time.Timer.Reset on the same timer instance from multiple goroutines? Or should these always be done in the same goroutine?

It is safe in the sense that the program will not crash and the timer
data structures will be fine. Of course it is unpredictable which
Reset will finally take effect.
