/* This object exploits the c++ guarantee that the destructor is always called, in order to deal with unanticipated shutdowns, such as the player clicking the X. However, it seems the destructor guarantee does not apply in some cases, such as ending the process using the task manager, or using ctrl+c from the console.

It seems that threads are killed if the user uses CTRL+C on the cmd line however, which messes things up a bit.
