Yay, since noone else has mentioned it, I get to add :) that the standard "why is minix interesting" nowadays is "it runs the Intel ME in a gazillion CPUs". That says something about what one bunch of Very Careful Engineers think about the implementation's uptime and reliability provenance... (The ME-cleaner project has identified that if Intel ME does not initialize, the CPU resets a few minutes after power on - so this suggests that a hard-unrecoverable error would leave the CPU unusable.)
