[Xcb] xlibs problem ;)

I am sorry to report that I was able to reproduce Jeremy's
GIMP hang problem with both stock Xcursor and Xrender and
the latest versions from freedesktop.org/xlibs :-).  Looks
like there's a bug somewhere.

Note that the GIMP uses threads to spin off an interpreter
for scripts, and this is where it is hanging...
