Yep. That's good for thaw. Doing clone by freeze/thaw OTOH doesn't help here. Neither freezing everything first (yielding an exact count - but generating the whole intermediate frozen image) nor freeze/thaw per PMC (with smaller images) does help here. Maybe we can get some statistics during a DOD run and keep that in an aggregate's header. leo
