            <title>[SERVER-46698] Invariant that operations which are holding open an oplog hole cannot call blocking functions</title>
                <link>https://jira.mongodb.org/browse/SERVER-46698</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;This is a theoretical class of liveness bugs where operations cannot be replicated if a recovery unit with its commit timestamp set is prevented from committing/aborting.&lt;/p&gt;

&lt;p&gt;Observing whether a recovery unit is keeping a hole open is relatively simple. The harder part is instrumenting all of the possible blocking calls. The initial version should strive to at least cover:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;Acquiring a lock&lt;/li&gt;
	&lt;li&gt;Acquiring a storage engine ticket&lt;/li&gt;
	&lt;li&gt;Acquiring a flow control ticket&lt;/li&gt;
&lt;/ul&gt;
