Dtors of static objects are run, exit hooks are called, etc.  In effect, all kernel threads are daemon threads, and D provides the option to get this behavior when it's necessary.  But if you have a daemon thread and want it to shutdown cleanly you need to take steps to do so.

Any thread spawned by the main thread will automatically get an OwnerTerminated or LinkTerminated message as soon as that app's main() routine exits, so the next time they do a receive() an exception will be thrown and they'll terminate cleanly.  Are you sure you need to use core.thread here?

But I don't need the funtionallity of std.concurrency, should I use it 
anyways?
