Yes, recent changes to the interpreter disabled the implicit abortion after 1000 interpreted steps, making the interpreter now either run infinitely or reaching the stack limit. I will work on this when I have free cycles.

This CL removes the {kRunSteps} concept, and instead allows to pass the number of steps to run to the Run() method. Step() just calls Run(1).
