If you think about delivery and quota long enough, the conclusion is that
it simply does not matter. I think I could show cases where accounting
tmp is both better and worse than not accounting it. The maildir quota
algorithm is broken for the sake of being lock free, but that usually
does not hurt. You can not fix it by accounting or ignoring tmp.

I vote for a similar mechanism to size determination to determine the ago
of files without stat(2). Account tmp and clean up old files found there,
which does much more towards a mostly correct result than ignoring tmp.
