I probably happened to have particularly pathological data structures with
respect to the work in the __gc metamethod. (I'm not necessarily thrilled
with that work either. It stemmed from efforts to manage per object
metatables.) It would still probably be a good idea to prevent the recursion
entirely.

I believe it was a table, but this hasn't been easily reproducible though it
has now fired twice. If there's a useful set of information I can collect
the next time it happens, let me know.

Thanks.
