As far as I understand, unsafePerformIO is not unsafe in relation to memory safety issues. It is just unsafe in that it circumvents the IO monad, which means order of execution is not guaranteed.

It's a different kind of unsafe, but my point is that it violates the normal guarantees of the language.
