   It'd be an idea to build a larger body of Python code to run the
profiling pass on so it doesn't just optimize the sort of code in
pystone which is not very representative. Could run the test suite as
it would have good coverage but would hit exceptional cases too
heavily. Other compilers (Intel?) support profile directed
optimization so would also benefit from such a body of code.
