I understand that 1.13 will let code run above the 4GiB (not 2) bar. (How does it get there?) It can even tolerate interrupts and redispatch from them. I suspect that from the developers' point that's a major advance. What goes in the IRB? Where does it keep the Grande OPSW? But no SVCs. Probably no system facilities understand 64-bit addresses. Likely the next step is SVCs, but the arguments will still need to reside below (even like access methods yet).
