I think there's a fundamental misunderstanding between the difference of an 
error code returned by a system call and the exit status of a process. They're 
two completely different things.

Just for fun, look at the man page for grep. It is advertised to return a 0, 1 
or 2. The actual values of errno that might happen in the middle are a 
separate problem.
