After writing this article back in October I receives dome feedback from
Bruce Hoult on the BDW GC mailing lists.  Based on his feedback I've written
a follow-up article
http://paul.bone.id.au/2016/12/29/more-about-memory-fragmentation/ which I
hope will also be interesting.

As before, Please let me know if I've gotten anything wrong, or of course if
you have any other comments.

I've put my changes to BDW GC in a pull request against master,
I have the same changes in a branch on my own github for the Mercury version
of BDW GC.  I'll back-port any feedback onto the Mercury version before I
commit it.

Have a happy new year.
