Thanks, I finally got around to looking at this and got similar performance 
results to yours.  That __attribute__((noinline)) bothers me, though, as it's 
not portable and is a bit inelegant.  I figured out a different way to avoid the 
inlining, and tweaked the commentary a bit, and so installed the attached 
additional patch after installing your patches.
