[pygtk] Does gobject.idle_add guarantee execution order?

[Christopher Backhouse]

If I do something like

gobject.idle_add(foo)
gobject.idle_add(must_run_after_foo)

Then am I guaranteed that these will indeed happen in the expected order?
Would be good to know before I base quite a lot of my application on 
this assumption (using idle_add to mean "I need all this stuff to get 
done, and in order, but not right now, and not the exclusion of user 
events")

Thanks
