    ...and one more fix for DbusIpcThread,
    
    switching back to a "Close" message-to-self without a response (as it had been
    before dc3ff192f3f048059cf149f416d0b237eb33b014 "Avoid further unwanted
    interference of DbusIpcThread::execute/close").  Especially on a first start of
    LO (where it restarts after creating the UserInstallation), it had been observed
    that DbusIpcThread::close was blocked waiting on a reply in
    dbus_connection_send_with_reply_and_block while DbusIpcThread::enable had
    already successfully (i.e., without emitting any of the SAL_WARNs) proceeded
    past sending the reply and was blocked on closeDone_.wait().  However that can
    happen---it should be clear by now that I don't understand anything at all about
    DBus.  :(
