Try pthread_cancel(). If you need to run some cleanup code in the target
thread, use pthread_cleanup_push. None of that would be with real-time
qualities, though. But I assume that the cleanup is not a time-critical
path, is it?
Sending a Linux signal would be another way to interrupt the target task.
