It's not marketed as a GC, but exit(2) is fast and effective when used as one.

I wouldn't call it a GC. It's more like an arena allocator, with the arenas managed by the OS :)

Now you've pushed the job of cleaning up page tables to the OS.

But that’s extremely easy - you go through a linear list once and free them all. You don’t even need to bring the contents from main memory to do it.

(Exception is shared pages, not used for heap memory often.)

It's definitely easier, because you don't have interior pointers. But it's still work :)

It's optimized for that, so just let it do its job.

The OS would have that job anyway.
