I've been expecting someone with actual experience in this area to jump in. I don't think you can get away with 'wait forever' logic. Eventually you'll get S522 abend. OTOH XCFAS, which preserves a permanent enqueue on LINKLIST libraries, seems to be very busy doing something, accumulating both CPU time and EXCP count. Maybe there's something on CBT?

Would it suffice to WAIT on an ECB that you never POSTed? Would this annoy WLM? Is there a better way? Should it intercept a STOP command and WTOR with an Abort/Retry/Ignore prompt?
