empty the duplicates databaes

[Michael Loftis]

Checkpoint lays down a marker of 'all transactions up to this marker are 
complete and in the tables'  recovery finds the last checkpoint, does a 
consistency check, then runs the transactions remaining after that forward 
until it gets to the end of the transactions logs.
