Possible clone issue

Dear DBI dev team,

I use DBI for several years and I'm happy with it! Now I may found an issue
when I call clone on a handle which was opened by connect_cached. I set the
private_data attribute, but it still returns the same handler. I'm not sure
if this is a feature or a bug.

Could you check my question on stackowerflow?

Thank you for your help!

Kind regards, TrueY
