Its really really useful It doesn't work reliably because the threading implementation might have to send signals which the current combination of credentials does not allow. IMHO, POSIX is wrong to favor process attributes so strongly. It wouldn't be a problem if there were other ways to pass these implicit parameters (such as thread-specific attributes, or, even better, syscall arguments). But often there isn't. - 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/ | ||||||||||||
