I know this is old, but I'm pretty sure it would fix a problem I'm seeing, is this change abandoned?

For anyone looking to use this right away, you can install Pycycle with this commit via:

pip install git+git://github.com/bndr/pycycle.git@44cd59843259cecc1b6f811c157733c5fcad16bd

This fixed the issue for me.
