ThreadSanitizer: data race lib/dns/catz.c:2257:2 in dns__catz_update_cb
Job #3270428 failed for 71f6ce0cafdd71cb720701e728c6e2e4f6587233.
This happened on bind-9.18-sub, so while I don't think it's the case, we just might be missing a bind-9.18 fix and a bind-9.18-sub rebase on top of bind-9.18 is all we need. !7705 (merged) is on the affected branch, tho.
