In reference to a message from John David Anglin, dated Sep 10:
> Have you looked at using stby or stdby for unaligned copies?
do you mean for the entire copy, or just to copy enough bytes to get it

i've thought about it, for replacing the copy-till-aligned bits, but
haven't tried... i always get confused when i try to understand how
those insns work :)
