            <title>[SERVER-37797] Modify the producer consumer queue to make it safe for multi-producer scenarios</title>
                <link>https://jira.mongodb.org/browse/SERVER-37797</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The producer consumer queue we currently have is useful, but doesn&apos;t have support for multiple producers.  A handful of small modifications will make it much more useful:&lt;/p&gt;

&lt;p&gt;1. Introduce a Pipe type which exposes the pcq as a producer end, a consumer end and an admin interface.&lt;/p&gt;

&lt;p&gt;2. Provide template params for the pcq so that we pay for multi-ness only for types that want it&lt;/p&gt;</description>

&lt;p&gt;Add support for MultiProducer + MultiConsumer on our existing PCQ and&lt;br/&gt;
introduce a Pipe type which holds the interface via shared_ptr ends and&lt;br/&gt;
closes those ends on destruction.&lt;br/&gt;
Branch: master&lt;br/&gt;
