Only the larger chunk may need to be overallocated if all allocations

I'd need a bit of convincing. I'm not sure everybody needs to pay for a 
few, and it is quite possible that malloc_align suffers from the same 
fragmentation issues as the next guy. Also, there's always the 
possibility of leaving some bits to lower-level functions.
