Yes I did..
I said I think they should just be redefined as 64 bit ints..
It's just my opinion. 64 bit page counts is ok but then 
most applications I know of would have to fetch that, fetch the
pagesize and multiply them together, and use the result.
(I've mostly seen this used in scripts and they are interested in 
"256MB" not "65536 pages")
