William Burns commented on ISPN-8946:
-------------------------------------

Note these changes will also try to avoid all unnecessary wrapping by subsequent interceptors (especially around iterator and supporting the remove method of it). These wrappings should be avoidable at all levels by setting the REMOTE_ITERATION flag as needed. Note only the highest level should provide the wrapping unless the flag was already set (by remote invocation such as LocalStreamManager.

> All places that override values returned from keySet and entrySet should always delegate appropriately to the underlying keySet or entrySet. We should try to be as minimally invasive to each level down as possible. An example would be that we shouldn't create copies of said collections if possible and instead just use delegates.
