We've had a few slack threads on these already:

They are essentially about these same failures just got on a build-neon job:

failures:
    v14::xlog_utils::tests::test_find_end_of_wal_crossing_segment_followed_by_small_one
    v14::xlog_utils::tests::test_find_end_of_wal_last_crossing_segment
    v14::xlog_utils::tests::test_find_end_of_wal_simple
    v15::xlog_utils::tests::test_find_end_of_wal_crossing_segment_followed_by_small_one
    v15::xlog_utils::tests::test_find_end_of_wal_last_crossing_segment
    v15::xlog_utils::tests::test_find_end_of_wal_simple

test result: FAILED. 25 passed; 6 failed; 0 ignored; 0 measured; 0 filtered out; finished in 2.16s

error: test failed, to rerun pass `-p postgres_ffi --lib`

These seem quite rare.
