This is a perfect example how "paranoid security" (sorry for using this term) prevents the use of desirable features. Do we want to forsake good resource management in favor of narrowing (not closing) one particular potential covert channel? As for me, the answer is no. (Actually, thinking about it, I'm not even sure the channel is narrowed at all; probably it just gets harder to extract the data, having no *explicit* indication of the system load.) -antrik- _______________________________________________ L4-hurd mailing list [email protected] http://lists.gnu.org/mailman/listinfo/l4-hurd
