## Interface Shareable

-     public interface Shareable

  A marker interface which allows you to put arbitrary objects into a `LocalMap`.

  Normally local maps only allow immutable objects or other copiable objects such as `Buffer` instances in order to avoid shared access to mutable state.

  However if you have an object that you know is thread-safe you can mark it with this interface and then you will be able to add it to `LocalMap` instances.

  Use this interface with caution.
