Assuming we want the yank feature (which I'm not entirely convinced
of), then I don't think any of this addition should exist. The
QIOChannel class already provides a "qio_channel_shutdown" method
which can be invoked. The layer above which is using the QIOChannel
should be calling this existing qio_channel_shutdown method in
response to any yank request.  The I/O layer shouldn't have any
direct dependancy on the yank feature.

Daniel
