Description

To better handle scenarios where a dispatcher dispatches from A to B and then back to A, and to clearly distinguish between the previous and next dispatcher objects, we need to add an epoch flag to the dispatcher.

This prevents the new dispatcher from receiving event data from the old dispatcher due to a failure to cancel the old dispatcher.
