This gives misleading information since the pointer is passed on the initial call to Eventually. It is not updated since <-stats returns a new pointer, rather than updating the data at the old pointer. Changed in favor of logging the relevant info as we get it.

TSMP ping counts as a "connection" in the agent stats so it never goes to zero. I'm not sure why we were testing it going to zero in the first place @code-asher

I think we wanted to make sure ConnectionCount was also updating correctly, but did not realize there would be other connections going on.
