> A flaky test has been discovered with recent modernizations of the sandbox
> components. It lives in 'nlp-utils' and the problem signals a fragile test
> setup or potentially numerical instabilities:

> The problem (sometimes) occurs on different platforms / environments (Win,
> Lin, Mac).
> Aims:
> * Investigate the cause of the flakyness
> * Fix the test (environment / setup) so it runs reliably.
