-For all functions that compose a new computation from children, if any child computations raise an exception, then the overall computation will trigger an exception. All computations that were started will receive a cancellation request.
+For all functions that compose a new computation from children, if any child computations raise an exception, then the overall computation will trigger an exception. The `CancellationToken` passed to the child computations will be triggered, and execution continues when all running children have cancelled execution.
