Lil' tweak to plugins using remove_thread. Just use remove_thread(NULL) to have a thread remove itself. No subsequent yield() is needed either. Small Note: in current scheduler implementation it safe to call remove_thread IFF 1) thread removes itself 2) its state is known to be running (1 implies 2) as any objects with the waiting removed thread will be corrupted (m->thread, q->thread no longer valid or no longer same object if recycled, etc.).
