select considers the broken pipe an error that needs reporting so it goes ready. Processes that are network aware normally set SIGPIPE to SIG_IGN. The default behaviour comes from a desire that non aware programs shouldn't get stuck spinning on a network error but go away.
If you ignore the signal you'll get a event from select, and then an error code. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
