I think it would be useful, even if it's not robust. I'd still like to 
know if a given two arrays COULD share data.

I suppose to really be robust, what I'd really want to know is if a 
given array shares data with ANY other array, i.e. could changing this 
mess something up? -- but I'm pretty sure that is next to impossible
