Maybe shoot a fresh email and directly CC various folks like howard, doug,
and nick? Seems reasonable to me.

I thought some of it still need libunwind (whichever of the various
versions you like)? It would be good to get a nice, clean implementation of
that functionality (whether based on one with an MIT license if there is
such or not) if we don't already have it.
