Description

Add a facility to the Core Thread that allows an IO-thread module to register for updates about a particular address.  Callbacks into the IO-thread (on an IO thread) shall inform the module about changes to the reachability of an address.

This can be used by a protocol listener to open or close the listening socket for a protocol listener based on the availability of remote connectors.
