Here's a mystery which I don't have time now to investigate, but I want to remember it for later.
Matlab has a constant open connection with.. itself.. through ports 4079 and 4080.  All I can find is that 4080 is associated with something called "lorica", and 4079 with "SANtools".  SANtools is a some sort of general utility for disc access, network storage..  I don't know what.  It's familiar, I've encountered SANtools somewhere before, but can't remember.  I have no idea what "lorica" could be.
Later.
