Perhaps you could connect to the "configure" event. You'd be able to get 
some code to run when the child does finally get its allocation. Sorry, 
not very helpful :-(

I think the delayed geometry management is generally a good thing: it 
helps reduce flicker, and usually speeds things up. You don't need so 
many of those annoying freeze()/thaw() pairs if you have to make a whole 
bunch of layout changes in a callback.
