#1412: Memory leak on development branch

 Priority:  major                  |   Milestone:

 I am seeing what appears to be a memory leak that has showed up since the
 Gauss release. I have run the same parameter file on Gauss and the
 development branch, and see linear growth in memory usage in the
 development version. From standard out it looks to be a bug in Carpet, as
 the memory usage jumps after re-gridding.

 I've attached:

 - The parameter file, bbhCart2-3.rpar. It runs on 12 cores on Datura.
 - Plots showing the memory usage per process in the two cases.
 - Standard out from the two cases.
