It fragmented parts of the email but got stuck somewhere and reported some like memory exhausted or can fork. To my believe these messages are bogus since I do have enough memory and swap and there kernel parameter are set to reasonable values. (BTW netscape was able to sent that mail without fragmenting in less than 10s.) So I thing there's lots of work left to deal with 32 bit addressable data efficiently. LP64 won't get you anything until you really hitting 32 bit architectural limits for (shared) memory, filesize and per process memory limits. Just for fun: Try to think of a 10GB XEmacs process catching a SIGKILL! It dump 10GB core image to disk which will take some time. :-)
