Adds a function to be called whenever there are no higher priority
events pending.
If the function returns G_SOURCE_REMOVE or false it is automatically
removed from the list of event sources and will not be called again.
See [memory management of sources][mainloop-memory-management] for details
on how to handle the return value and memory management of data.
This internally creates a main loop source using glib.global.idleSourceNew
and attaches it to the global #GMainContext using glib.source.Source.attach, so
the callback will be invoked in whichever thread is running that main
context. You can do these steps manually if you need greater control or to
use a custom main context.
