Before any code block is run, it checks the modified time on attached 
files.  If the modified time is newer than the last time we ran it, it 
runs the file again before running the code block.  So I think it can do 
its work in the pre-run-code hook.

But Thomas is right that this conversation should probably moved to the 
ipython mailing list.
