"- One object going out of scope may mean calling free once, but it also can trigger calling free billions of objects, even for the exact same object

- Even freeing one object can have largely varying running time, e.g. to coalesce free blocks or, because it happens to be the last block in a virtual memory region, to unmap a block of virtual memory, blocking the program potentially for an arbitrary time"

So, like C, C++, or anything else that you wouldn't call garbage collected.
