memtest is a utility for testing the memory subsystem in a computer to
determine if it is faulty. The original source was by Simon Kirby
<sim@stormix.com>. I have by this time completely rewritten the original
source, and added many additional tests to help catch borderline memory. I
also rewrote the original tests (which catch mainly memory bits which are stuck
permanently high or low) so that they run approximately an order of magnitude
faster.
