I haven't checked this with the code, so take it with a grain of salt.

The callbacks should be registered in the continuation which should be
registered in the session. So unregistering a session should make them
all eligible for garbage collection. The callbacks should implicitly
become invalid once the session is unregistered because the lookup
first looks up the session. If the session can't be found you
shouldn't be able find and therefore execute the callbacks.

TL;DR everything should just work but you might want to check in the
code yourself ;-)
