#### Description [src]

Dereferences use count of the `key` by `dec_ref_counts` and removes it from the cache when the reference count reaches zero. Special case is with `dec_ref_counts` is zero, in which case the key is removed regardless of the current reference count.

It’s not an error when the key doesn’t exist in the cache.
