committed deleted row space reclamation may be missed if delete is actually an 
aborted insert.

         Key: DERBY-691
         URL: http://issues.apache.org/jira/browse/DERBY-691
     Project: Derby
        Type: Improvement
    Reporter: Mike Matrigali


The system should queue post commit activity in the case of an aborted insert 
which internally is implemented as a delete.  In this case post commit should 
be queued following the same rules as straight line delete currently.  The 
result is that if the last  delete on a page is actually an aborted insert then 
space on that page may never be automatically reclaimed (It is always can be 
reclaimed by hand using the space reclamation system procedures).
