Memory protection for one, zSeries hardware prevents one task from getting to another tasks memory. I know on the Intel platform this must be handled by the OS, so this is more instructions that the OS must execute and more work done by the CPU. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
