No, I think it would be fine to only send the output after
btl_openib_if_in|exclude is applied. Perhaps we need an MCA param to
say "always send everything" in the case that someone applies a non-
homogeneous if_in|exclude set of values...?
When is carto stuff applied? Is that what you're really asking about?
