It put a big smile on my face too, but I am not so surprised.

In programs manipulating binaries, we've often experienced such speedups
(typically 8x) over BEAM when using HiPE, and judging from Edwin's post,
this appears to be a binary-intensive program. (Of course I _will_ be
very surprised if the speedup is due to some reason other than binaries.)

But having the program is a good thing nonetheless.
