Now Now Now...not quite so hasty.  There are extensions to Unix' that make
doing real time work easier.  I think your following comments are more along
the lines of Unix has more overhead then Intuit. which is very true.  But it
also is more portable (even BSD to ATT) then any set of micro OS.
A curious though that just came to mind is that Ada is suppose to be part of
the POSIX standard....Ada is (suppose to) react to certain real time stimili
so I think that implies that POSIX will be able to be used for real time
tasks...???

Personal gripe: The acronym MIPS has no real hard meaning.  It is a relative
measurement that is not relative to anything easily tied down....
