The failed_unittests_gather.sh is a setup task which should only run on certain unittests tasks. Right it was added to our broad spectrum compile task group as a setup task. This means its executed on every compile tasks in all our compile task groups. Within the script itself it will check the task name and noop out on non unittests tasks.

This is confusing and obscure. The setup task should be moved to the tasks themselves so that its clear when the scripts executes and so that it only executes when needed (eliminating the noop cycles).
