I realize this is the way the MPI library is designed, but I'm wondering if it possible to use some C++ goodness to make the request objects persist behind-the-scenes until the request is completed? The behavior is particularly unexpected in the Python layer. Thanks very much! " Feature Requests closed Boost 1.37.0 mpi Boost 1.36.0 Problem duplicate
