Comment (by carter):

 Which of these plans of attack are more likely (well, until benchmarks say
 otherwise) to also have a positive impact on 64-bit systems?  (i'm
 similarly neutral about 32bit performance, but if theres some work that
 could have positive fallout for both, that'd be a good starting point)
