Daemon threads will keep running until the process terminates.  Forcibly halting them any earlier risks leaving mutexes they hold in a locked state, etc, which could break shutdown and hang the app.  Typically, you'll want to have a shared module dtor communicate to any daemon threads that it's time for them to halt, and block until a response is received if you want to ensure a clean shutdown.
