  Thanks for the pointers, Jim, I'll take a look at that: if I just need to
backport the setup code and the rest should fall into place and work, that
sounds not too hard.  Whether what I've backported will be enough to
consider the 3.2 loop optimiser production-stable... I guess that's another
question.

  Now please accept my humble apologies for bringing back the memory of what
seems to have been a traumatic time for everyone and let us never speak of
this again!


    cheers,
