Many apologies.  I broke the criterion for running global GC when I added
the allocation measurement support.  The GC is run when the heap is found
to have grown by some ration (default 1.5) after each scavenge.  When I
added the allocation counting support I noticed that there was a bug in the
determination of the size of the heap (the old code just looked at the
extent of the heap, not the sum of the size of segments) and so I changed
it to use the correct size.  Evidently I've broken something.  I'll fix it
asap, but first have some other issues to attend to.  It should be fixed
before the end of the week.
