So am I, but, for example, we don't have any of the long time GCC
developers doing design/implementation reviews on that branch right now.
That's a very different situation than what you would find on the
tree-ssa branch where Richard, Jason and myself work with Diego,
Andrew, Jan, Zdenek on design and implementation issues.
I'm not saying that we shouldn't be looking to merge LNO, I'm saying I
think David's schedule is far too aggressive.
