IMHO, mutt is broken for relying on atimes because other programs
reading the mailbox will cause mutt to miss new mail.  It would be
silly to solve the problem by demanding that all those programs use
O_NOATIME.  But that doesn't mean rsync shouldn't offer O_NOATIME...

Nobody has bothered to implement it yet.  It wouldn't be hard to do.
