The Short Answer

Programs that are "Not Responding" aka taking forever to shut down or actually frozen, usually make use of multiple processes and/or threads. Today's software applications are not usually linear (take for example your word processing app or instant messenger) as they require a lot of concurrent tasks to be done in the background (Google docs saves everything as you type in the words, your internet browser has a lot of tabs open each responding to different requests etc.) It is when a thread or a process takes longer than expected to execute their function that such a thing happens. Data also needs to be saved. This is one of the major reasons behind exiting taking so long. Games have this problem along with other applications that use databases.
