Also I think in this case, faster random is a slightly better choice. There seems to be nothing cryptographic about this sleep_time.

This PR should be closed in my opinion.

Thanks for the interest @gjskha, but yeah, as others point out, this is not needed here. So I'll close this one. But thanks for the interest! ☕
