I believe the issue here has to do with when query snapshots get frozen.
This is something we've mucked about with repeatedly --- 7.2 is
different from either 7.1 or 7.3, IIRC. But I'm not sure if 7.3 fixes
your problem or not. Would you be willing to boil down your example into
a self-contained test case that we could run to study the behavior?
