Right. We already have the full blown threads one in std.parallelism. What
I'm saying is that, if you're using threads, you're already assuming
associativity. Therefore, you may as well use ILP and loop unrolling, too.
std.parallelism currently doesn't do this and once we work out the details and
create an assocReduce in std.algorithm, these techniques should be ported to
