 This probably doesn't *completely* solve the issue, because a single download
can be very large as well.

 We discussed this at the hackaton and decided that it would be more appropriate
to instead tweak the number of files to delete from the download directory. By
setting that number very high, you can approximate the same result (except that
the git repos will never be touched). The code changes for that would be a lot
simpler we think, and we think it's more suitable as an option.

 Therefore, we've marked the patch as rejected in patchwork. Feel free to
implement the suggestion above instead (or, of course, keep this as an
out-of-tree patch).

 Regards,
 Arnout
