            <title>[SERVER-28028] reinstate std::timed_mutex</title>
                <link>https://jira.mongodb.org/browse/SERVER-28028</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Since we no longer build with Gcc &amp;lt;4.9, there is apparently, at least by the comment in stdx/mutex.h, no longer a reason to ban std::timed_mutex.&lt;/p&gt;

&lt;p&gt;Is there any reason to retain stdx/mutex.h at all?  Or should uses be changed back to &amp;lt;mutex&amp;gt; and std::mutex?&lt;/p&gt;</description>

                            <comment id="1500513" author="schwerin" created="Thu, 16 Feb 2017 21:15:23 +0000"  >&lt;p&gt;I&apos;m not certain we should be using timed_mutex at all. timed_mutex implies that you might have mutexes that are held for a long time, which is strongly discouraged in the mongodb codebase. The preferred course of action is to use a lock in the lock manager, or to do your waiting on condition variables, as both are interruptible via the checkForInterrupt mechanism.&lt;/p&gt;

&lt;p&gt;If all our stdx concurrency types can switch to std at this point, that would be fine, but I&apos;m not sure that comment is an exhaustive list of problems.&lt;/p&gt;</comment>
