I haven't done any real tests (That is, commented out your new code
again to check against the old implementation) but on my KDE system I
seem to get more flickering now then I got before. But this is comparing
the current behaviour with my memory of the old one, which isn't that
reliable.
The system is OpenSuse 11.4 with what ever version of kdm that comes
with it. Most likely KDE just doesn't support that protocol and things
are the same as the always have been :-(

I committed a patch on the weekend implementing the _NET_WM_SYNC_REQUEST

There isn't much info about it on the web; the best I could find is from the Qt
blog: http://labs.qt.nokia.com/2009/06/10/smooth-and-solid-resizing-on-x11/
Resizing feels a lot better to me now. The window contents and window manager's
frame stay together about as well as GTK now - not perfect, but better than
before.
When using the window manager's window decorations (i.e.
GSBackHandlesWindowDecorations is not NO) my patch had the side effect of
getting rid of the black flashing when resizing. I was seeing the entire window
repeatedly flash solid black while resizing. I saw this in all WM's I tried
(windowmaker, metacity, enlightenment 0.17). Were other people seeing this as
well? Is it gone now?
When resizing using the GNUstep provided window border the black flashing is
still present, though, so we should probably try to figure out what's causing
that.
