Simplehash provides an option to provide your own allocator function
to it. So in the allocator function, you can allocate memory from DSA.
After it reaches some threshold it expands the size (double) and it
will again call the allocator function to allocate the bigger memory.
You can refer pagetable_allocate in tidbitmap.c.
