Hwloc supports mac topology (not binding because osx doesn't (publicly) support binding).
But I definitely agree that soak time is necessary. I put a timeout of about 2 weeks; I thought that should be enough. But there's really no rush.

Subject: Re: [OMPI devel] RFC: Remove all other paffinity components
Umm...I vote "no". I still need that "test" component to use when testing paffinity on machines that don't have all the required support (e.g., Mac).
I don't have an opinion on the other components.

Once we get any kinks worked out, I propose removing all the other paffinity components and leaving only hwloc.
