Memory is a relatively scarce resource on many consumer computers, so a feature to limit how much memory a process uses seems like a good idea, and Microsoft did indeed implement such a feature. KiPageFault is triggered whenever a process touches memory that is not currently in the working set of the process. That is remarkable.
