T568-lib-thread assums that there will always be a thread with ID thread:0000000000000009, but this turns out not to be the case. This was reported to us in Nixpkgs[1], where it caused builds of our notmuch package to intermittently fail, and I was able to (intermittently) reproduce. We are going to work around this problem for now by disabling T568. I can provide a Xapian DB generated by this test with no thread with that ID if that's helpful. I believe this also explains this report previously sent to the Notmuch mailing list[2]. Note on reproducing: I found that it often would succeed repeatedly many, many times before failing, and then failing consistently for a while. My co-conspirator Puck (CCed) thinks this might be due to how directory order works in ZFS (which just happens to be the filesystem we are using).
