The reason for a file descriptor is so that I can also add other
file-like objects, such as StringIO.  My unit tests, for instance,
rely heavily on this.  That being said, it is not *strictly* required
(my unit tests could be modified to write to temporary files), but I
thought it was a nice feature.
