Many other allocators follow similar patterns.
Ah, ok, that makes sense. I was thinking more in terms of the whole
program running out of memory, not fallback.
One more illustration of the same idea: just completed a larger doc.

The Kernighan-Ritchie allocator is composed of a list of blocks, each
organized as a free list; when one block gets exhausted, the list
detects that and allocates more.
