Getting off topic here but "normal" isn't always "desirable." Some might say that allocating singletons and never
freeingthem - even after they're no longer valid - is just sloppy code. By the same logic, dangling pointers are A-OK,
solong as you never use them. So yes, it might be an extra cycle or two to free it now, but that's a cycle or two the
OSwon't have to do later, and it's almost certainly better to have a cleaner codebase that's 0.000001% slower.
Or so some might argue. :)
