I played with that idea but wasn't as patient as you. :)  The problem  
that stopped me is siblings.  Say you have a function that calls  
do_foo() and then do_bar(), each of which set up progress bars.  If  
those are each "top" in your example, then at the end of do_foo(),  
the bar is at 90%, after which it will suddenly drop back to 80% again.

If the bars subdivide in this manner, each level of a function stack  
needs to track it, possibly adding its own progress bar to the mix.   
Maybe this is the right thing to do.  But it's something to be aware of.
