Abstract: Every modern operating system provides some form of virtual memory
to its applications. Usually, a hardware memory management unit (MMU) exists to
efficiently support this. Although most operating systems allow user programs
to indirectly control the MMU, few programs or programming languages actually
make use of this facility. This article explores how the MMU can be used to
enhance memory handling for resizable arrays. A reference implementation in
C++ demonstrates its usability and superiority compared to
the standard C++ vector class, and how to combine the scheme
with an object-oriented environment. A number of other improvements, based on
newly emerged insights in C++ are also presented.
