Yes, our last compile was being done with -O2, basically. 
However, PyPy's backend-optimizations are not switched 
on (with problems probably related to the exception 
handling problem mentioned in the day 6 report) and
this makes the life of GCC's register allocator 
quite difficult (according to Samuele's guesses).
