On the other hand, the sleep fits better to the test description, "should allow reading stdout after a few milliseconds". Even if 1 != 'a few'. It's possible the part of the commit reverted here, https://github.com/oven-sh/bun/commit/a42bf70139980c4d13cc55..., defeated the purpose of the test by removing the sleep. I don't think adding the sleep back is an example of AI cheating.

Strange test though either way.
