commit f47c806f6736a269d02846de77996ff199354394
Author: Rob Latham <robl at mcs.anl.gov>
Date:   Tue Jul 2 18:41:52 2013 +0000

    small memory management cleanups
    
    missed a free of an unused array in one case, and freed some arrays
    immediately after calling MPI_Alltoallv in an attempt to chip away at
    memory footprint.
