Bruce, for the low-level impared such as myself, can you give a quick precis on teh difference between "fast" interrupt handlers in -current and 'normal' interrupt handlers. Do fast interrupt handlers enter through "trap()" ? if they interrupt a user process, do they take on the cred of the running thread? do they return via doreti() on returning do they check for ASTs and run userret()? I have seen the answers to some of these questions in the code, but I'd like to get a more 'english' explanation from someone who seems to understand them..
