This issue seems to be caused by the contacts generated during the modify contact pass having a restitution that's not based on the material values of the shapes colliding. If you go through and set every contact to it's expected restitution (and friction?) value in every modify contact callback the issue resolves itself.
I think this is a real bug. Having non-expected contact properties in the modify callback forces those values back into the real simulation if you don't correct them yourself.
Even with this fix the simulation isn't quite as smooth as with modify contacts disabled. I think this is probably as good as I can get it now, but if there are any further recommendations for how to stabilize my scene that'd be appreciated.

Hi @kujukuju
Thanks for the detailed report. I've created an internal issue. We'll check it and fix in one of the next releases.
