Thanks, @rapidsna. I agree with what you said here. (I also agree with @rjmccall.) I don't want to make anymore changes to this patch though. As @nathanchance pointed out, this is holding up Linux testing / development and I want to submit it soon. I believe it's ready for submission.

To be honest, this patch was only meant as a bug fix, but snowballed out of all proportions. However, I think it's in a state where we could submit this and continue development from there.

I need to point out that this *isn't* the last patch in this feature. I'll have more to follow. Can someone please just give approval so that we can get on with life?
