Because it means we'd still, by default, have to delete on
failure. Otherwise you'd end up with an endless number of such partial
directories.  There's really no reason to do delete a failed directory
ever, since the space usage is obviously bound.

As there appears to be no benefit in the randomness of these
directories, why work on retaining it?
