  Blah, I joined two different output runs and grabbed the wrong parts.

msimons@star:~$ ( ./ascript 3>&2 2>&1 1>&3 ) 2> /dev/null
something on stderr
msimons@star:~$ ( ./ascript 3>&2 2>&1 1>&3 ) 1> /dev/null
something on stdout
msimons@star:~$ 

  You can see from the last two sample that "2> /dev/null" throws
away the scripts command's stdout...
