Brian Barrett 5b9fa7e998 reapply r15517 and r15520, which were removed in r15527 so that I could get 
the RML/OOB merge in slightly easier

This commit was SVN r15530.

The following SVN revision numbers were found above:
  r15517 --> open-mpi/ompi@41977fcc95
  r15520 --> open-mpi/ompi@9cbc9df1b8
  r15527 --> open-mpi/ompi@2d17dd9516
