XtraDB changed page tracking

Hi Guys

Any one successfully setup this feature(XtraDB changed page tracking).

We are currently evaluating Percona 5.6 & I cannot use this feature to speed up my incremental backups.

Looks like this feature is broken at least with Percona 5.6.16 & 5.6.17.

A bug was already filed here(https://bugs.launchpad.net/percona-server/+bug/1323889)

You can see my findings in the 3rd comment.

Thanks & Regards
