  1440.                    We cannot lock or do jack operations during jack callbacks on jack1. jack2 events are asynchronous.

  1441.                    When we close the client jack will trigger unregister-port callbacks, which we handle on a separate thread ASAP.

  1442.                    But before that happens we already registered a new client with the same ports (the "renamed" one),

  1443.                     and at this point the port we receive during that callback is actually the new one from the new client..

  1444.                    JACK2 seems to be reusing ports to save space, which is understandable.

  1445.                    Anyway, this means we have to remove all our port-related data before the new client ports are created.

  1446.                    (we also stop the separate jack-events thread to avoid any race conditions while modying our port data) */
