emulating du with os.walk

Firs of all, I don't know how much you already know about os.walk, but it 
can traverse trees either top-down or bottom-up (it has an argument 
'topdown').  The default is topdown=True.  What you probably need in your 
case is a bottom-up traversal (so pass topdown=False).

Then you have to keep track of all the directories (I can suggest a data 
structure if you want) and add the du values of all the children directories 
plus the sizes of all the files to determine the du value of a parent 
directory.

Without seeing your code, I'm guessing you are not doing one of these 
things.
