These properties control whether the worker threads are daemon threads. A daemon thread is automatically terminated when all non-daemon threads have terminated. A non-daemon thread will prevent a program from terminating as long as it has not terminated.

If any TaskPool with non-daemon threads is active, either stop or finish must be called on it before the program can terminate.

The worker treads in the TaskPool instance returned by the taskPool property are daemon by default. The worker threads of manually instantiated task pools are non-daemon by default.

Note: For a size zero pool, the getter arbitrarily returns true and the setter has no effect.
