I notice that rankfile didn't compile properly on some platforms and
issued warnings on other platforms. Thanks to Ralph for cleaning it
1. I see a getenv("slot_list") in the MPI side of the code; it looks
like $slot_list is set by the odls for the MPI process. Why isn't it
an MCA parameter? That's what all other values passed by the orted to
the MPI process appear to be.
2. I see that ompi_mpi_params.c is now registering 2 rmaps-level MCA
parameters. Why? Shouldn't these be in ORTE somewhere?
