This is just a Linux ecosystem thing. Other full size operating systems do memory accounting differently, and are able to correctly communicate when more memory is not available.

There are functions on many C allocators that are explicitly for non-trivial allocation scenarios, but what major operating system malloc implementation returns NULL? MSVC’s docs reserve the right to return NULL, but the actual code is not capable of doing so (because it would be a security nightmare).
