Chris and Chambers,

Thanks a ton for looking at beta 31 for me.  I was able to get a hold of beta 30
from a kindly user, so I'll be able to include POV-Ray results, although they
are slightly outdated I suppose.

Just to add a comment on 64b vs. 32b performance, the major differences:
1.  16 registers vs. 8
2.  64 bit pointers vs. 32b pointers
3.  >4GB of memory

2 is a subtle point - it substantially increases the pressure on caches and
TLBs, since cache lines are fixed size (64B).

David
