`wait_until` allowed 200 × 10 ms — exactly the 2 s `backoff_start` the reopen
path spends before it can succeed. On a warm, idle machine it wins the race;
on a cold binary or a loaded box it does not, and `reopens_after_push_death`
failed 3 of ~5 cold runs while gating this branch. CI is always cold.
Six seconds costs nothing when the test passes and only delays a genuine
failure, so the budget now clears the backoff with room to spare.
