> On allocation failures, it's useful to know where the memory is being used in
> the tree of allocators (for debugging). One way to do this would be by adding
> APIs to :
> # get root allocator from a given allocator
> # get summary of usage/limit from an allocator upto N levels (N is an input
> arg)
