ummm... send it a certain signal with pthread_kill() (and setting up something like thread::flag == END_OF_WORK_BABY at the same time but only in case when there can be other cases of getting a signal by this thread)? In such a case, read() should return -EINTR.
Note, a signal handler must be installed without a SA_RESTART flag so that the read() will not be restarted after signal processing.
