OK, I think this has reached the stage where it's been polished enough outside mainline to the point where we can complete any remaining todo items in-tree. So lets begin merging with the minimal target core and the TCM_Loop as two separate commits. I think the target core may just fit under the reflector mail length limits, but if not, you can send it as multiple patches and I'll recombine them.
