Indeed, if the peer does not respond, the actual tear down of the
connection will last until the timeout is reached, but as far as I
know, this does not prevent from completing the cleanup and applying
the new configuration.

Well, I think the new conf can be used immediately (the old connection
will just survive for a while until the timeout is reached). I'll try
to do a little test.
