Revert "Merge pull request #12060 from Vexu/IterableDir"

This reverts commit da94227f783ec3c92859c4713b80a668f1183f96, reversing
changes made to 8f943b3d33432a26b7e242c1181e4220ed400501.

I was against this change originally, but decided to approve it to keep
an open mind. After a year of trying it in practice, I firmly believe
that the previous way of doing it was better.
