I haven't gone over the Windows side yet.  The Linux side looks reasonable.

Actually, after Brian's recent examination of the hwloc source, there aren't any outstanding bugs in hwloc that are cause for concern.  So we do plan to migrate in the direction of using it.   We have other logistical issues to work out before we use it internally. so we don't plan to propose a switch over to it here for some time yet, and it should be considered experimental for now (but perhaps stern warnings aren't needed).
