j|�d aXWdQRXWdQRXdS)aA decorator for functions which create a glib event loop to keep
Python signal handlers working while the event loop is idling.
In case an OS signal is received will wake the default event loop up
shortly so that any registered Python signal handlers registered through
signal.signal() can run.
Works on Windows but needs Python 3.5+.
In case the wrapped function is not called from the main thread it will be
called as is and it will not wake up the default loop for signals.

Only does something if called from the main thread.
In case of nested context managers the signal handler will be only
installed once and the callbacks will be called in the reverse order
of their registration.
The old signal handler will be restored in case no signal handler is
registered while the context is active.
