Johnny, If you are running disabled, then you are the machine and you better know what you are doing.
Getting 'disabled' is not something a normal program can do, you have to be authorized. Getting rights to be authorized means you can then do just about anything you want, and you had better be careful. So to answer the questions, once disabled the system has no way to interrupt you and you can starve everyone else out.

Or it cannot and just let my TCB starve other users? I cannot figure out. -- Best Regards, Johnny Luo ---------------------------------------------------------------------- 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
