[issue6116] frame.f_locals keeps references to things for too long

I think you misunderstood the bug report. The issue here is not that locals are referenced from the dict, it's that the dict is kept alive (since it is cached) longer that it should.

By the way, reading the discussion again, I think we could simply make dicts weak-referenceable. A dict is already quite big in memory and I don't think adding a pointer to the struct would make a significant difference.
