So, bottom line: There are no "leftovers" when an address space terminates.
*If* the address space terminates. But, the question was about "jobs", so the AS will stay around until the initiator is stopped.
So, theoretically, an authorized program can get some storage and
assign ownership to some task above the job step task (there are also
some subpools which exist for the life of the address space). If that program does not free the storage upon termination it will then only be freed when the owning task ends.
There's also possiblity to view memory from HMC.
BTW: That's why so called secure cryptography does use dedicated hardware for key storage. Unencrypted key cannot reside in main memory, because it could be intercepted.
