​It's too bad that RENT implies "read only". It makes complete sense that
REFR does. IIRC, back in the very old days, there was the "SVC transient"
area (2K or 4K) into which an type 3 SVC or one of the parts of a type 4
SVC was dynamically loaded. ​These modules were "refreshable" which I think
meant "MVS, you are allowed to refetch this module from disk and just
continue running it because I guarantee that the code & data areas in it
are not ever going to change".
