        <pre>wl_data_device interface does not have a destructor defined in the protocol,
which means that the server cannot know if a client destroys a wl_data_device
object. This leaks the server-side resource.

To make things worse, wl_data_device.data_offer *event* creates a new
wl_data_offer protocol object.

If a client has destroyed a wl_data_device, the server will not know about it,
and will keep sending data_offer events as appropriate. As the client does not
track the wl_data_device object anymore, those events will be ignored in the
client. This means that in the server, wl_data_offer objects just keep piling
up, as the server cannot destroy them on its own.

If possible, we should add destructor protocol to wl_data_device interface.</pre>
