FWIW, I have been trying to add this to the interpreter VM. Adding the necessary
primitives is straightforward, just adopt the necessary primitives in
InterpreterPrimitives from Cog and adapt them to the trunk platform sources.
But there is additional support needed in the interpreter to signal the image
at appropriate times to collect profiling data, and this is a bit less trivial.
I don't know if I'll have a working implementation any time soon, but I'm trying,
and I'll probably follow up with a few dumb questions on vm-dev as to how it's
supposed to work.
