I've been experimenting with with some gcc options and features. What  
I found out so far is that with the options -fprofile-generate and - 
fprofile-use I was able to increase the Richards and pystone  
benchmark results (on top of pypy-c) with a little over 15%.  
Stackless is currently still 10-15% slower compared to plain vanilla  
PyPy, but I have some idea that I would like to look into in the next  
couple of days to make that better.
