Problems with writing on closed pipe exceptions using os.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. download the pgw dictionary
2. run   cat /lib/dict/pgwindex  | os awk '{print $1}' | sed 100q 

What is the expected output? What do you see instead?

I'd expect the command to terminate. Instead it stays in permanently stuck 
status. I think this is a 
problem with  the difference between Sys and things run in limbo modules. When 
OS handles an 
exception it doesn't propagate back to the shell.

I'm seeing the problem with:

  cat /lib/dict/pgwindex  | getlines {
    (word nil)=`{echo $line}
    echo $word
}| sed 100q 

as well. This indicates that's its not quite the problem I expected.
