I admit, I don't use custom allocators as much as I should and am 
not as experienced in this topic as others, yet for my purposes 
this design seems excellent. The docs are solid, and I really 
like the idea of just being able to composite something like 
AllocatorWithStats. The use cases I had in mind (which are 
admittedly quite simple) are covered, and it's very clear how to 
add a custom allocator if desired.

A couple of questions:
Shouldn't most of these implementations be marked nothrow? I 
could be missing something here.
For CAllocator, I notice setting alignment is a property yet does 
not return void. Does this not go against the idea of @property? 
Perhaps it should be setAlignment instead?
