We are running it in production since Friday and haven't had any
crasher, so it's looking good! I had planned to wait until
Thursday/Friday to report back. Overall, I am highly confident that the
patch fixes it, we had at least one crash a day before.

Yes, I think setting to NULL it the simplest approach to take in the
short term. And we haven't seen any performance degradation on our
search layer since.
