If context is currently blocking in g_main_context_iteration()
waiting for a source to become ready, cause it to stop blocking
and return. Otherwise, cause the next invocation of
g_main_context_iteration() to return without blocking.
This API is useful for low-level control over GMainContext; for
example, integrating it with main loop implementations such as
GMainLoop.
Another related use for this function is when implementing a main
