Even at 500MB, it fits easily in a 31-bit address space. Even a couple of them 
do.

I think this was IBM's attitude for some time -- "really? why?"

I think perhaps things like CICS want to be able to fit lots and lots of big 
application programs -- I have seen 180,000 line COBOL programs -- resident in 
a single region.
