Description

The integration tests create several directories with a few hundred files. This was motivated by the original implementation of `DeleteDir` and `DeleteDirContents` which used the own thread pools to delete the objects. I wanted to exercise the flow control code in those thread pools.

During the review apitrou proposed a much better design, which does not need explicit flow control, and therefore does not need these large directories. Reducing the size of these directories would reduce the running time to a few seconds.
