Actually, most of this was fixed in -current by SMPng, by moving interrupt threads to having seperate stacks. The KSE code affects this by moving the non-pcb part of struct user into a seperate location, which caused only about 600 bytes to be stolen instead of 3000+. I moved things around so that the pcb is above the stack and there is an unmapped guard page below the stack so that we are pretty well guaranteed to get a double fault on a stack overflow.
