Must be one heck of an emulator. Everytime I've seen an emulator for hardware
that is significantly different, as is the case here, the slowdown was *huge*.
Of course, I have no idea what it would yield emualted on a PC, but since
Chrilly said that he could do things on his hardware that would have a heavy
cost on a PC, I suspect that an emulated Hydra on a PC would be quite weak.
