commit 3b330831cf996926482c4fe7f7941d3c8d0686b8
Author: Devendar Bureddy <devendar at mellanox.com>
Date:   Sat Oct 25 03:04:00 2014 +0300

    Fix for threaded_sr
    
    Do not block in mxm for blocking sends. Instead , set req pointer let
    MPICH mpi layer to block on it. This will allow progress go to through
    MPIDI_CH3I_Progress(), which can release the global mutex in thread
    multiple case.
