      Description

      If you have a large folder and delete it, all jobs inside are first deleted. This could take a while (minutes?) if you have the Job Config History plugin installed, or generally if I/O is slow:

      Note that the monitor is being held on the Folder while deleting its children. This means that view threads can hang during the process:
