Changes to aio of a connected CS and possibly others require the CS to
be disconnected, which in turn means the engine gets shut down and the
jack connections are lost.

It's not the purpose of jack-session to reconnect the client in such a
case. Jack connections are supposed to be under the users direct
control, using a connection manager of sorts. Jack-sessions also assumes
this is the case. It's not designed to make non-persistent connections
'magically' persistent. Therefor to make ecasound work with jack-session
ecasound must first behave properly, which means it needs persistent
jack connections.

Sorry if that's a little long and complicated :)

And more dirt to come :)
