OK, newest benchmarks show a stable 32% speedup at richards.py, even
working on the trunk - you just need to enable the strdict flag like this
in the target:

    config.objspace.std.withstrdict = True

This gives the following factors for pypy-c vs. cpython (measured on
pypy2):
Richards: 2.98x as slow
PyStone: 3.5x as slow

Now I am looking forward to have someone building an LLVM/C/Profile guided
opt binary with strdicts enabled :-)

Kind regards,
Alexander
