MySQL cannot erase data

For eight years it has been known (and Verified) that MySQL does not release diskspace it has claimed in its ibdatax files. The bug leads to full disks and database outages since the only way arround it is to shut down the DB, dump it (consuming even more space) scrubbing the disk and restoring from dump.

This is a veritable showstopper.
