commit 16005083a56c442d3a0c167d65544b73f60bc044
Author: Pavan Balaji <balaji at mcs.anl.gov>
Date:   Sun Feb 9 19:40:45 2014 -0600

    Remove overly conservative assertion.
    
    MPI_COMM_IDUP currently just asserts out when we use it in
    multithreaded mode.  This is overly conservative.  MPI_COMM_IDUP works
    fine in such modes unless it is executed concurrently with another
    routine that also tries to allocate or free a context ID.  Removing
    this assertion till we find a more appropriate way of tracking this
    error.
    
    Fixes #2020.
