Don't use daemon threads, they are inherently un-thread-safe: any global access you do anywhere inside a daemon thread can fail, because daemon threads are still potentially run during interpreter shutdown, when globals are being deleted from every module. Most functions you might call are not safe in a daemon thread at shutdown.
Given the use-case (must shut down, cannot risk a hung process, orphan files be damned) I don't think having a daemon thread die because it raised an exception trying to access a missing global is a big deal.
