Can rsync assume that the destination directory is empty ?

There isn't an option for that and it isn't actually required that the
target directory be empty (just a good idea). Plus it has to do the
stat calls on the other end anyway so I doubt there would be much
Maybe --ignore-times would cause it to not look but I kinda doubt it and
I am too tired to do an strace right now ;)
