commit 89ec5ecf2c5d7694ced255188fa10133f9c6a496
Author: Pavan Balaji <balaji at mcs.anl.gov>
Date:   Sat Feb 22 16:16:59 2014 -0600

    Replace comm_free with comm_disconnect.
    The original comm_free was incorrect as the parent process was
    disconnecting the connection to the child, but the child was not
    disconnecting it's end.
    Thanks to Charles Archer @ Intel for reporting the error and providing
    the patch.
