Comment (by bgamari):

 To be clear, while I agree that this is an important issue, 8.0.2 needs to
 leave the dock at some point soon as 8.2.1 is on the horizon. I'm okay
 with pushing the 8.0.2 release off by up to two weeks for this, but at
 that point I will really need to release it regardless of whether this
 issue is fixed.

 I am working with Oleg to get our OS X test box running Sierra, but I
 can't make any promises about being able to fix this myself. It would be
 quite helpful if someone could summarize the proposed solution.

 Even better, it would be amazing if someone with an affected machine and
 knowledge of dynamic linking on OS X (a small set, I know!) could take
 ownership of this issue and carry it to solution. This may be darchon, but
 I'm a bit worried what might happen if he doesn't have time to finish,
 October 10th arrives, and we have no solution.
