            <title>[SERVER-19846] Remove existing usages of timed_mutex and disallow new uses</title>
                <link>https://jira.mongodb.org/browse/SERVER-19846</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;We have had two non-trivial issues related to std::timed_mutex, see &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-19759&quot; title=&quot;add a configure check for std::timed_mutex&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-19759&quot;&gt;&lt;del&gt;SERVER-19759&lt;/del&gt;&lt;/a&gt; and &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-19535&quot; title=&quot;Capped collections grow unbounded under WiredTiger&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-19535&quot;&gt;&lt;del&gt;SERVER-19535&lt;/del&gt;&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;We should remove all existing usages of std::timed_mutex and disallow novel usages. For situations where we must use timed_mutex, we should use boost::timed_mutex under NOLINT.&lt;/p&gt;</description>

In so doing, we actually made the timed_mutex safe to replace with a stdx::mutex, dropping the timeout. We only had the lock acquisition time limit because we needed it for the distributed lock variant, and it was easier to have symmetry in the two implementations.&lt;/p&gt;</comment>

&lt;p&gt;I&apos;d have to refer to &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=spencer&quot; class=&quot;user-hover&quot; rel=&quot;spencer&quot;&gt;spencer&lt;/a&gt; or &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=schwerin&quot; class=&quot;user-hover&quot; rel=&quot;schwerin&quot;&gt;schwerin&lt;/a&gt; to answer if it/how it can be removed.&lt;/p&gt;</comment>
