***********************
Communicator Resources
***********************

Resource handles owned by a :py:class:`Communicator`. They share a common
lifecycle: each handle is tracked by its owning communicator and is
released either explicitly via its ``close()`` method or automatically
when the communicator is destroyed or aborted.
