Posting here for Eric since he wrote the original patch.

I'm not sure we needed the grandparent check to begin with -- we pass the test
without it. Eric, can we just remove it entirely? Do you have a testcase where
we crash with a NULL grandparent?

This patch preserves the grandparent check but localizes it to code paths that
require it.
