If resume continued to run through a disconnect/reconnect
cycle then a race would be caused by c.stop = make(chan struct{})
Likely to be a rare issue in production (a lot of messages persisted,
slow store, and/or fast reconnect).
Also to enable tests to be run with the race detector
Test_ConnectRetry has been updated to avoid a race.
Probably closes #362 (cannot be sure becasue issue does ont provide sufficient detail)
