Note that there may still be D-Bus traffic to process (relating to this
signal subscription) in the current thread-default #GMainContext after this
function has returned. You should continue to iterate the #GMainContext
until the #GDestroyNotify function passed to
g_dbus_connection_signal_subscribe() is called, in order to avoid memory
leaks through callbacks queued on the #GMainContext after it’s stopped being
iterated.
