Plan to get started with `libc++abi` as soon as I'm done with `libc++`, I've hit a couple of bumps with the latter, resolving them at the moment.

I don't see any new `pthread` dependencies introduced in this patch, so it sounds OK to me. Thanks for the ping though!

The patch itself looks OK to me. Will need approval from @mclow.lists or @ericwf.
