[Glass] Finding instances of old (removed) classes

[Paul DeBruicker via Glass]

I'm not sure.  Exploring, I guess.

I think I have some instances that are exhibiting old behavior.  So I'm
trying to clean up orphaned classes to see if that fixes the instances
behavior problems.  

But it could also be a different bug I haven't found yet.
