>
> When thread-safe per superstep output is used, in the end of application we
> close all the writers in a single thread. Closing a writer can take time, and
> we are not reporting progress while doing so, so it happens that tasks
> timeout during this stage. Doing it in multiple threads and calling progress
> while doing it will make it faster and prevent tasks from timing out.
