This ref needs to be removed after every timeout event. ping-timer mechanism could be holding the last ref. For e.g, when a peer is detached and its rpc object was unref'd. In this case, ping-timer mechanism would try to acquire conn->mutex to perform the 'last' unref while being inside the critical section already. This will result in a deadlock.
