         If the lane is still running after the timeout expired, there is a chance lanes will freeze forever at shutdown when failing to terminate all free-running lanes within the specified timeout.

         This means the execution of the lane will resume although the operation has not completed, to give the lane a chance to detect cancellation (even in the case the code waits on a <a href="#lindas">linda</a> with infinite timeout).
