I thought one of the benefits of not having the round trip at
swapbuffers time was to allow applications to continue executing until
they actually needed the new buffer names.

We can still do that and have DRI2CopyRegion return a reply, it just
means making the Xlib-based extension library a bit smarter and able to
store the CopyRegion reply until the client needs the contents. XCB, of
course, will automatically do this for us.
