"size" and "count" are set, even we got a race. Thus we should use them for the
quota check. (Under conditions of a heavy flood I'd be happy to see the quota
mechanism kicking in eventually.) It is just the "maildirsize" file what is
deleted since we saw a race during the recalculation process, and we dont want
to leave an inaccurate maildirsize file.

That's what the ensure_maildir_size_file() in tf_maildir.c does.
