| People are generally not aware of the properties of daemon threads. I suggest to add a note such as the following: « Daemon threads are abruptly stopped at shutdown. Their resources (such as open files, database transactions, etc.) may not be released properly. If you want your threads to stop gracefully, make them non-daemonic and use a suitable signalling mechanism such as an Event. » | ||

| +1 This is essentially the answer to the naive user's question: "Why would anyone *not* use daemon threads given that they're less hassle to manage?" | ||
