I haven't read the Maildir spec in a while, but isn't Maildir defined
such that the new->cur move must be one of (a) an atomic rename()
operation or (b) a hard-link operation so the file appears in both new
and cur, then an unlink from new?

If one of the above is the case, then at no time should a message not
exist in at least one of new/cur, and if we check new first, then cur,
we should be guaranteed to find any message that's there.

Or, is there some hole in my reasoning?
