I know this doesn't solve it for many sites, but I should add that
4.3 will truncate directories for you automatically. Each time an
entry is added to a directory, excess space is removed. So if a
directory grows huge, and you then remove everything from it, it
is still huge. But when you next add something, the directory will
shrink.
