            <title>[SERVER-40003] Change opCtx waits to always use the fastclock</title>
                <link>https://jira.mongodb.org/browse/SERVER-40003</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Inside the opCtx code, maxtimems and runWithDeadline times are tracked with the fast clock, but opCtx waits are tracked with the precise clock.&lt;/p&gt;

&lt;p&gt;If it&apos;s okay to use the fast clock for hasDeadlineExpired, it&apos;s probably okay to use it for timed waits, and we could save ourselves some cycles if it is.&lt;/p&gt;</description>

Current fixVersion is &quot;features we&apos;re not sure of&quot; to reflect that.&lt;/p&gt;</comment>
                            <comment id="2175275" author="schwerin" created="Thu, 7 Mar 2019 23:16:15 +0000"  >&lt;p&gt;The condvar wait used to involve asking the OS to do the waiting, so using its clock (the precise clock) seemed less susceptible to bugs from skew between the two clock sources. Just be careful.&lt;/p&gt;</comment>
