Ok, now I see what you mean, and I agree with your analysis (but you are 
using the technical terms "child" and "parent" rather unorthodoxly wrt 
your book on Linux Programming ;) : what really count here, is that, 
when an "ate" open fails, we close the fail and return error (i.e., 
null). The other process is not doing anything useful.
