[Glass] Does findAllReferencePathsToObject:maxPaths: in GS 3.3.1 ever end?

[Paul Baumann]

Check to see if they are instances of an older class in class history,
perhaps referenced by class variable or class instance variable of older
class editions.

Add more paths if your CPU has spare threads for use, search will complete
faster unless disk IO constrained.
