Chris,

Thanks for your testing.

So I would conclude from this that with icc on a p3, there is very 
little improvement going from zlib 1.1.4 to infnew-3.  However I would 
also conclude that icc does a noticeably better job than whatever 
compiled libz.so (gcc?).  Is those the correct conclusions?
