I think an allocator that uses your chain buffer for storage and is safe could be a good thing. I think that the allocator can be implemented in a way that it doesn't need non-static data members. The chain is in and of itself not interesting as a replacement for deque, but as a memory buffer for a good allocator I think it could find its niche. I'd like to see the memory buffer implement object deallocation and memory reuse, and perhaps thread saftey (maybe optional thread safety enabled by default). I almost coded up a proposal for such an allocator based on a deque when I last replied to you, but I see you've thought way further along those lines without my prompting.
Now that is a great idea! A boost::allocators library would be a great addition. Then everyone wins, because we could have a cross-platform stack_based_allocator and monotonic_allocator and the like.
