I picked up a book this weekend on the native Windows API - there's a 
function called "ZwMapViewOfSection". The docs say:
"When mapping pagefile and datasections, BasedAddress and SSection Offset must
be aligned with the system's allocation granularity unless the AllocationType
flags include AT_ROUND_TO_PAGE; in which case, they are rounded down to the
next page boundary."

As soon as I finish my CS757 midproject-report I was going to play around 
with writing a bit of code to see if this really works or not....
