Summary: USE_CACHE_ALIGNED still helpful?

Initial Comment:
Jack asked for this report:

"""
MacPython uses it. At the time it was put in it caused 
a 15% increase in Pystones because dictionary entries 
were aligned in cache lines. But: this was in the PPC 
601 and 604 era, I must say that I've never tested 
whether it made any difference on G3 and G4.

Put in a bug report in my name, and one day I'll get 
around to  testing whether it still makes a difference 
on current hardware and rip it out if it doesn't.
