I keep meaning to get back to you about this; sorry it's taken me so long.

I wrote the tokenize-based code before I saw your importchecker.py code; I'd 
decided to go with the tokenize module instead of the compiler package since 
the later was poorly documented (IMHO).  I've no really strong feeling about 
either approach being better.

I'm not sure simply re-implementing one of the finddeps.py internal interfaces 
is the right thing to do; that's some incredibly cludgey code in Zope 3.  
There's a lot of confusion about what values are paths and which are module 
names, and that makes me very uncomfortable.

If you'd like to replace the code that locates imports, feel free to do so.  
It may be that conciseness wins; the tokenize-based approach certainly ended 
up being more code than I'd expected initially.

No, Martijn's talking about something else... kinda.  I imagine he had even 
stronger feelings about your initial implementation.  ;-)
