It might be interesting to see the numbers with the latest gcc.  It used 
to be that there was a 10%-20% performance improvement running V9 binaries
over V8 binaries despite the larger memory use and increased cache 
footprint.  This could theoretically be improved even more if gcc were 
smart enough to use prefetch instructions and non-faulting loads.
