Comment:
OK, this was one of those weird bugs that was only reproducible in
doctests, and an all around pain to track down. Apparently the coercion
changes caused some parents to not get garbage collected as eagerly, which
exposed a bug when fgp modules are cached and reused. I am still unsure
what exactly the bug is (I have a hunch it has to do with parents that are
defined in doctests getting reused in other doctests after their
environment has been recycled or something) but I have disabled caching
for now to get it to work.
I refreshed the exposure-fixes patch, should work fine now.
