# TODO: 2016-7-30 mblayman - Since the 2.6 signature is no longer relevant,

# Module level state stinks, but this is the only way to keep compatibility
# with Python 2.6. The best place for the tracker is as an instance variable
# on the runner, but __init__ is so different that it is not easy to create
# a runner that satisfies every supported Python version.
