823	Seekable file_descriptor_source /sink?	gmsb	Jonathan Turkanis	"{{{
The supplied file_descriptor_source and file_descriptor_sink are not seekable. Is this an oversight?

For file_descriptor_source, all that appears to be needed is changing from:

    struct category : public source_tag, closable_tag { };

to:

    struct category
      : input_seekable,
        device_tag,
        closable_tag
    { };

and adding:

    using file_descriptor::seek;

Similarly for file_descriptor_sink.
