=== Stopping Programs ===

- **never** stop a not hanging program with //ctrl+c//
 - when a restart of the program is really necessary use .q instead
 - restarting a program is in most cases not a solution and only increase the risk to trigger more problems. So avoid restarting programs as long as possible
