Not that I know of; you can try searching bugs.python.org, though, to verify.
 
Would it be better to integrate larger dataset sizes into difflib or to create something new such as bigdifflib?

This would be overkill for a new module. Patches are welcome if you would like to propose a solution for the pre-existing difflib module.

=== Rather than modify difflib.py, I modified the diff.py command line interface that appears in the Python doc. I am sure that some of my clumsy code could be improved.
