Do we truncate mmap() values to the nearest page so to not confuse the user? ;)
Imagine a careful application setting and accounting for limits on a long-running system. Might its internal accounting get sufficiently misaligned from the kernel's after a while to cause a problem? Truncating values like that would appear reserve significantly less memory than desired over a long period of time.
