The issue here is that the GPIO API does not allow us to read back the
state of output GPIOs (even though for almost all hardware this is
supported by the underlying hardware).  With the GPIO API as it stands
it is unfortunately not possible to preserve the state, if the API were
fixed we'd preserve state.
