System V/MLS is still being used in a few places today.  It was
available on the 3B2 (we32k and mips versions) and x86 platforms.  It
was certified C2 and B1.  The government had a contractual requirement
for MLS, but access controls seemed like a good idea anyway.  The
constraints of MLS affected usability and made it difficult to sell.
