In my shell I have avoided the dup() call.
In order to get the same goal
I have done an UGLY stderr=stdout=stdin;
I can share the same socket while the shell task is running.
dup() spents the limited FILE table resources.
No very correct but works.
This kind of tricks are the same thing that
the COMMON BLOCK in fortran versus the structured procedural
programming avoiding the global variable side effect.

I am not very happy with the bad notice of Joel's father.
