            <title>[SERVER-3481] interrupting --eval while(true){ ; } loops using killOp</title>
                <link>https://jira.mongodb.org/browse/SERVER-3481</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;On my fast system (and infrequently on some buildbots), it takes a long time (potentially forever) to kill while(true){} spinlocks sent to the mongod server.  This seems to especially occur when using v8, seems as if the kill operation just is not able to progress.  Adding a sleep(1) statement to the while() loop fixes the problem.&lt;/p&gt;

&lt;p&gt;While currently the problem only shows up in tests, potentially an accidentally buggy $where query may be unable to be terminated on a user&apos;s system while hogging the cpu.  &lt;/p&gt;</description>

It should work better now.&lt;br/&gt;
Only possible issue is that empty loops can be optimized to have no stack guard, and v8 relies on that for interruption.&lt;/p&gt;</comment>
