Use 'open' instead of the deprecated 'file' (removed in 3.x) and use it 
with a 'with' statement (this is now standard). This closes the file at 
the end of the block. Not doing so can cause problems on other 
implementations.

                 with open(path, 'rb') as fo:

Do you know how to use queue.Queue to spread work to multiple worker 
threads so each processes different files (and to collect results from 
multiple threads).? (If not, read doc.)
