Formatting changes done in NUMA will probably get left out of the merge. I'm ok with that because I probably did the formatting changes and I'm probably the one who is going to be merging them back, so I'll leave out things that aren't essential. 

As far as merging things back now, I know that this may well make my life more difficult when merging the NUMA branch back into trunk, but we're going to wait until 2.5 is released to make the changes. I just don't want to risk derailing the release of 2.5 by breaking the trunk. I probably could take some of the code contained in 


and safely move it back now, but most of this code can be merged back fairly easily, and I doubt this will save me a lot in the long run. For now, I think its best if we wait for more testing and refining of the code before merging anything back in.
