S)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.

Installs a SIGINT signal handler in case the default Python one is
    active which calls 'callback' in case the signal occurs.

    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.
