g_io_add_watch () only allows you to know when when something changes on
the file descriptor associated with the channel (from my experience).

I think the reason for not being notified when you have been
disconnected, is because GIOChannels are used for handling file
descriptors and file (for example) never has a disconnected state.

In the past, when I have wanted to know if I have been disconnected I
have looked out for:
        - G_IO_NVAL | G_IO_ERR
        - G_IO_HUP
        - G_IO_STATUS_ERROR returned from g_io_channel_read_chars ()
        - 0 bytes returned from g_io_channel_read_chars ()
