Windows is not "waiting" for me to render. It just closes the clipboard.
If we do nothing on receiving WM_RENDERALLFORMATS, the clipboard is
actually kept empty, because using the delayed-rendering-way we have
already called EmptyClipboard() in handle_clipboard_grab(). I think
doing nothing is the right thing here.

MSDN is saying: "WM_RENDERALLFORMATS Message is sent to the clipboard

place the data on the clipboard by calling the SetClipboardData function. "
When our agent is killed, do we really want to send a REQUEST to the
client? I see no reason to render in this case or keep the clipboard
available for other apps.
That indeed seems a bit silly. Isn't windows waiting for you to render
something though? You could just set the data to a zero size block.
