Thank you for the work.

Just as the commit message mentioned --
"dbus_connection_open_private() itself is still synchronous", I did
find some dbus_connection_open_private() failures in my debugging
before(though at a very low occurrence rate). -- that's why I chose
the thread way.

Also, the shutdown_connection() may block in theory, since it invokes
dbus_connection_flush()
