Then good luck with that; seems to me like a recipe for wrecking your repo in case two unfortunate souls do svn commit at the same time.

Now I know that cloning groups is supposed to work (it requires that all the primitives within the group are themselves cloneable, but you've got that covered), but I've never used it myself and can't say for sure that it's working as advertised. But it's supposed to, and if it is not, please let Andrew know. Cheers, Florian
