Right... Actually I believe that it would be useful to manually export on the
'file' class only the attributes and methods of self.fd that officially exist.  
At least that would be coherent with the point of view that 'file' instances
should have only the official attributes.  In this case, you have to define a
bunch of wrapper methods and properties to access the underlying self.fd
attribute's methods and attributes.

But this could also be regarded as overkill...  I'm not sure I care too much
one way or another.
