enhance derby inplace compress defragment phase to hold locks for less time.
----------------------------------------------------------------------------

         Key: DERBY-1188
         URL: http://issues.apache.org/jira/browse/DERBY-1188
     Project: Derby
        Type: Improvement

  Components: Store  
    Versions: 10.1.1.0, 10.1.1.1, 10.1.1.2, 10.1.2.0, 10.1.2.1, 10.1.2.2, 10.1.2.3, 10.2.0.0
   
    Reporter: Mike Matrigali
    Priority: Minor


Currently the truncate defragment pass holds locks until it commits.  It would be better if
it committed more often.  To do this
the loop must be enhanced to pick up ddl level state change when the commits happen and release
locks.  It may be that
work being done in 10.2 for scrollable updatable result sets across commits in open cursors
will help with this.
