    gegl-init: Don't abort on multiple gegl_init,gegl_exit invokations
    
    global_time was not reset in gegl_exit(), so the assertion in
    gegl_init() would fail the second time around.
    
    Note: There still seems to be some dirty state after gegl_exit(), as warnings like
    "Warning: Two different plugins tried to register 'GeglChantconvert-format_c'."
    are outputted.
