> Need support to compact lob data files after a certain threshold is reached .
> Deleting or updating a table with lob columns cn cause the lob datafiles to
> be left with unused holes. These need to be compacted regularly.
> TO simplify the flow of execution, the mxlobsrvr process functionality is
> being moved into the master executor. There is no need for a spearate process
> anymore since there isn't going to be a separate storage engine that may need
> to make calls to this process. The lob file processing can all be done in
> the master process itself.
