@ -7,3 +7,11 @@ teardown of the previous connection; so the new session-listener
responds to the assertions from the old connection before the old
connection has a chance to die. Of course, it *does* die (since commit
11de40c), but having that zombie reborn new session is annoying.
- This is thorny. You'd think that having a session wait for its
line-reader to go would be enough, but the multiple nested
during/spawns creating the sessions mean that no matter how long
the old session instance sticks around, a new session will appear
before we're ready! ... maybe there's no way *at all* to
disambiguate old/new instances without, say, a unique
listener-socket identifier??
