Maybe that (thread creation) can be done at open(), socket-creation, service request, syscall or whatever event triggers a driver/subsystem to actually queue work into a thread. And when there is a close(), socket-destruction, service completion or whatever these threads can be marked for destruction and destroyed by a timer or even immediately.
