Did you replace the whole switch statement with a dispatch table? That
sounds like a sensible thing to do anyway.

OTOH, if this is for ruby 1.8.x, I'm afraid you may not find much interest
in such changes while the focus is all on 1.9.

Perhaps worth checking how 1.9's bytecode interpreter stacks up under the
same conditions?

OTOH, 1.9 doesn't have callcc anyway, so maybe your application code would
need a lot of restructuring to use Fiber instead. I don't know if it's
possible to implement callcc in terms of Fiber.
