Memory leak when using atomFamily/selectorFamily

See original GitHub issue

Hello there,

The resources created by atomFamily and selectorFamily are not being properly freed when the specific key changes or if the component using the related RecoilState<T> unmounts.

Since I believe that memory management isn’t properly implemented yet, both utils should be marked as _UNSAFE.

Just FYI we are working on the memory issue with use of family utils, and should have something to announce about it in the near future.

Could this be related? I am getting this warning and cannot seem to figure out a way to get rid of it.

Warning: Can't perform a React state update on an unmounted component. This is a no-op, but it indicates a memory leak in your application. To fix, cancel all subscriptions and asynchronous tasks in a useEffect cleanup function.
