The question was not about the millisecond typo, but about why time-out at all. We would need to somehow break out of poll() after handling the SIGCHLD signal and I guess timing the syscall out would be the most obvious way, but somehow it felt awkward. Another way would be to set up a pipe to ourself that is included in the poll() and write a byte to the pipe from the signal handler. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
