Maybe he was talking about a freelist allocator over a reap, as
described by the HeapLayers project http://heaplayers.org/ in the
paper from 2001 titled 'Composing High-Performance Memory
Allocators'. I'm pretty sure that web site was referenced in the
talk. A few publications there are from Andrei.

I agree that D should support programming without a GC, with
different GCs than the default one, and custom allocators, and
that features which demand a GC will be troublesome.
