There was a problem hiding this comment.
This line causes a data race with lines 229 and 247. Is it really needed to set it to nil when the timers are stopped?

This fixes two leaking goroutines from the ringpop timers. There is still one more leaking goroutine that I'm aware of in rcrowley/go-metrics:

That's a ticker that would also require a stop channel.
