- It doesn't. The data is mapped into the second quadrant, which is private
- (not shared with other processes). The text is mapped into the 3rd or 4th
- quadrant, which is shared with all processes. But when it is mapped by
- the first process that uses it, it can be placed anywhere within the 3rd
- or 4th quadrant.
