Improve Memory Management #163
Description
Things can go wrong and jobs can terminate abruptly. If the caller does not get a reference to the job back or does not invoke job.destroy() windows can remain open indefinitely. This results in memory leaks as the process continues to run.
Windows that remain open beyond a specified threshold should be automatically terminated. Subsequently, the owning job should also be freed up for garbage collection.
There should be a new event that clients can observe when this happens
