I've tried and failed mizerably. :)
I've been told its a major speedup as well, but despite pulling every
trick i can to align everything, I havent seen any speedups as a result.
At the moment, i'm concentrating on making my 'memory in order' patches
hit the tree, and then we'll be working toward the same goal (a
single-invoke feature extractor), because I think we'll have more speed
improvements from that than from me continuing to bang my head on
alignment issues. Its on the TODO, however. :)
