Dan,

earning my money by working in refineries and all kinds of other 
chemical plants, I can assure you that it is _very_ unlikely that one of 
them will explode because of a failed *NIX service. :) You wouldn't get 
a permission to start your plant up in the first place if it was 
designed to rely on a service being up all the time.

Windows machines and *NIX workstations are used for process 
visualization only in these environments. I/O with the field is done by 
(usually redundant) modules running well known (i.e. rather old) 
software and on top of this you usually have failsafe PLCs (Programmable 
Logic Controllers) that override the control system in case of an emergency.

Of course, this might be different in countries like North Korea or so...
