Any other detail to reproduce this failure?

The binding test succeeds and runs fast for me in the same environment.

The issue is caused by: https://github.com/zeroc-ice/ice/blob/ac98b4fcb9979f0709f1524fde28937cc521fe3d/scripts/tests/Ice/binding.py#L17

Without the setrlimit, it works fine.

Despite the comment, it's not clear to me why we set this limit.
