We found another solution to changing the magic constant "UseOldAfsCalls".
So it is not strictly necessary to make the previously advocated change.
Although it would indeed save a few microseconds on the first AFS call,
we discovered it was a mis-aligned pointer in user code that was
panic'ing the PMAX. Perhaps we should send an SPR to DEC encouraging
them to signal EFAULT when there's a mis-aligned pointer provided as an
argument to longjmp.
