Stop/start the notify main thread at the right level
Stop/start the notify main thread at the right level

The thread is stopped/started in wins_prepare/unprepare_external() when hooks
are run. There is no need to do it in io_reload_data(). In fact, because of the
nested calls

notify_stop_main_thread() <--- io_reload_data()
...
	notify_stop_main_thread() <--- hook/wins_prepare_external()
	...
	notify_start_main_thread() <--- hook/wins_unprepare_external()
...
notify_start_main_thread() <--- io_reload_data()

the thread has been running after the first hook anyway.
