Make sure LogikSim either recovers or crashes on error instead of hanging #44
Description
Currently a lot of error conditions leave LogikSim hanging. This is most likely due to threads not started as daemon still running in the background. To resolve this:
- Make sure threads are started as daemon
- Make sure we log when a daemon thread terminates for some other reason than a clean exit. Don't rely on it being terminated for us during normal operations.
- Make sure crashes in important threads are noticed and reacted to by the application
