before: 15773 pystones, 29.9 mPB
after:  12690 pystones, 31.4 mPB

Switch back to CVS:

19531, 19379, 19531, 19379, 19305, 19084 pystones, 31.4 mPB

Switch back to Tim's patch:

15015, 15480, 14588 pystones

should not need, but:
make clean && make  (just make on previous, only listobject.c being recompiled)

Still patched: 
13158, 14006, 13193; restart python; 15923, 16722, 16023
restart python; 12953, 13698, 12953, 13513

Well, pystones are all over the map on this box.  But the improvement is there
for punchit and the parrotbench benchmark is solid across the change.
