   I'd like to know whether it was intentional that you performed
   the test with such an old version instead of new one.

 | mind when I first tried to explain the disparity between your results
 | and mine).  I expect that code to recognize this will be reintroduced

 | in systems where multiple return values are like your MU anyway but
 | with extra overhead.

Although I understand that it is possible to momentarily forget things, it is
quite discomforting to come to these realizations now.  I still have a
difficult time understanding how such an important detail could be overlooked.
