Flaky test: checkin::probe a_later_slow_bind_does_not_extend_an_earlier_listener#4072
Failed on CI run 42891133510 (rust-tests cli-1) for a PR that doesn't touch checkin:
| 1 | panicked at crates/ployz/src/checkin/probe_tests.rs:723:5: |
| 2 | assertion failed: bindable(second) |
The test asserts a second port is bindable right after the earlier listener's window; on a loaded runner that port can still be held.
Score: F 3 (CI only, intermittent) × S 2 (rerun fixes it) = 6.
