You don't have so much virtual addresses, as they are not allocated on a byte
per byte basis, but in bunches (64K or 16M), depending of the use.  The system
is consuming many temporary addresses for its own work.
I suspect the V4R4 to be able to allocate 1 TB with only one virtual address
for the so-called UNIX teraspace, but I'm not sure...

That's true, the RISC system has so many addresses, they don't need to be
reused:
look at the WRKSYSSTS, the temporary address percentage will increase for the
life
of the machine, with or without IPL, even thru releases.
