Paver: fail if pylint/pep8 violations threshold is breached.

This is the piece I want to work out. As it's currently coded, paver will quiet with a failure if the violations limit is breached. Ok that's cool, but this also means paver will completely fail & skip any remaining tasks that were passed in.

Do you have any suggestions on a way to make paver "wait to fail" until all the tasks have completed?
