In test_basic_concurrent we sometimes see:

    Error: bundle status not received within 10 attempts

    Location:
        tests/e2e/mod.rs:99:24

   DELAY 2/4 by   1.992s relay::tests e2e::cases::transactions::test_basic_concurrent
   RETRY 2/4 [         ] relay::tests e2e::cases::transactions::test_basic_concurrent
