So shift the cutoff param to the MPI layer, and have it solely determine whether or not we call modex_recv on the hostname. If comm_world is of size greater than the cutoff, then we don't automatically retrieve the hostname when we build the ompi_proc_t for a process - instead, we fill the hostname entry on first call to modex_recv for that process. The param is now "ompi_hostname_cutoff=N", where N=number of procs for cutoff. Refs trac:3729 This commit was SVN r29056.
