Hmm.  I'm not sure.  What would making Zero available upstream mean 
exactly for OpenJDK 6?  I'm inferring Zero in is sufficiently new 
versions of HotSpot (hs17 vs hs16) given the presence of a src/cpu/zero 
directory in the JDK 7 HotSpot repo.  Would the rough proposal be to 
port the Zero fixes applied to hs17 in JDK 7 to the hs16 in OpenJDK 6?
