I think I've unnecessarily overstated my case, which has put both of us 
in defensive.

You are very right that tests on D1 and D2 are not comparable. And 
Walter has at one point made crucial changes in the allocator at my 
behest. Specifically, he introduced in-place growth whenever possible 
and added the expand() primitive to the gc. These are present in D2 but 
I don't know whether and when he has regressed those to D1. (And btw why 
wouldn't you try it :o).)
