LXRES dates back to MVS/370 SP1.2. RESMGR did not exist until MVS/ESA SP3.1.0. LX and Entry Table cleanup is done by a static task termination resource manager which is called only when the terminating TCB is a Cross Memory Resource Owning Task (i.e., the TCB address matches the contents of ASCBXTCB). To quote myself, "The CMROT (whose address is in ASCBXTCB) is always the jobstep task of the started task or job, regardless of which task actually does the LXRES and ETCON."
