With the possible exception of a true real time system.

GUI means nothing other than the RT routine is running ) and
likely by the minimum hardware requirements. ( lots and
lots of RAM, for instance, and real fast CPU's plus the idea that
anything with a hard disk can't, by definition, be *true* real time )
( well, it can, sorta, but takes even more RAM, and l-o-n-g
relative deadlines )
(( hey, if the deadline is next week, even Windows can be RT ))
I'm with Fred on this. Reducing the "error" to the point of
unnoticed insignificance is more realistic, and should be
