I am aware of that - I never intended this class to be used 'by users' ;).
Its a kludge, used internally by my library, exclusively in debug code,
for one specific task: writing debug output to a pipe(2), indeed by only
using operator<< in the few (fixed) lines where it is used.

If it is added to some FAQ as "general file descriptor class", then please
don't add my name to it -- I got a reputation to keep up of "only writing
robust, bug free code" ;).

The given uflow method is not conforming to the standard either if I remember
correctly... I did remove code from it that I had written at first because I
realized it would never be used anyway in my case.
