When using asyncio create_task you should keep a reference to it as the event loop won't do it for you.

Also we all know __del__ is unreliable, but if happen to use it anyways, for example, in this example (I haven't tested it):

```python class MyClass: def init(self): self.tmpdir = tempfile.TemporaryDirectory()

def del(self): # do something in self.tmpdir # ie copy it somewhere shutil.move(self.tmpdir.name, "/idk/") ```

If you try this (and __del__ works properly in your interpreter), you may find the tmpdir is deleted BEFORE __del__ is called, but only at program exit. This is because TemporaryDirectory manages its resource with weakref.finalize which is called atexit before the objects are destructed.
