Take a look at dcollections' chunk allocator, which is under boost

starting point.
One difference from this allocator vs. the generic ones you are
implementing is that it's templated on the type being allocated. It's
intended to be used for a collection, which only allocates one type (a
node). Does this kind of thinking belong in phobos? I'm not sure. But I
think we can at least reuse the free list implementation.

Hmm, your chunk allocator looks like a generalization of
FreeListAllocator. If I get around to implementing FreeListAllocator,
I'll add support for allocating chunks instead of one element per heap
allocation.
Well, I think the GC already uses free lists... What would be the point
of one on top of that, especially if the "block size" is constant?
