crossbeam-rs__crossbeam-1101 | Thanks for the report!
IIUC, insert reduces the refcount of the old value and then sets the new value, so if insert makes the refcount zero, a get that occurs between the time the refcount is reduced and the new value is set will return None because it sees a deleted value with a refcount of zero.

Now that `std::atomic::AtomicU{8,16,32,64}` has been stabilized, please allow `AtomicCell` to store values with non-`usize` widths without a lock.
This would require increasing the min rust version. Let me know if you like me to send a pull request.
