a91c6275 introduces flushing ui buffers after a worker finished. If the ui was not flushed before the worker was started, fork will copy the existing buffers to the worker. This causes messages issued before the worker started to be written to the terminal for each worker. We are now flushing the ui before we start a worker and add an appropriate test which will fail before this patch.
