The protocol isn't blocking, only the library interface is. You can
either use an event or a reply to let the client know when the data are
done; the reply is more sensible in many ways as it parallels the existing
GetImage infrastructure. An event would make it easier to have an
asynchronous API in Xlib, but it is possible to make replies asynchronous
as well.
