I've never understood why, after all these years, IBM hasn't put the quick-post code right into the POST macro. Of course there are special cases (XM post, most obviously), but the macro normally knows if it's a simple POST. Is there any case where it is desirable to issue the SVC (or otherwise call POST)? Is it to cover the case where the task being POSTed has a higher dispatching priority, and should therefore run first, before the POSTing task runs again? Surely this is a long obsolete application design, after thirty years of multiprocessor machines being in common use.
