Hi Eliot,

Was Andreas' profiler fully functional on an Interpreter generated from oscog
at one point? I know that Andreas had done at least an initial implementation
in that part of the code. I had assumed that his main focus in that time frame
would have been on Cog, so I was not entirely sure if the Interpreter
implementation was complete.

Of course I was trying to adopt the implementation from the oscog branch
when I looked at this last year. But given that I was not successful, I
won't attempt to argue that this was the best possible approach.

Thanks,
Dave
