Hudson commented on JENA-157:
-----------------------------

Integrated in Jena_ARQ #487 (See [https://builds.apache.org/job/Jena_ARQ/487/])
    JENA-157 - This adds a pre-merge phase to SortedDataBag to merge files 100 
at the time max. If more than 100 files need to be merged, it is done in 
multiple rounds. (Revision 1298851)

     Result = SUCCESS

> The DataBag implementations need to perform a pre-merge of the spill files if 
> there are a large number (say more than 100).  Otherwise too many resources 
> are used (file handles and input buffers).  See [1] for more info.
