But in general it's impossible to tell at configure time which
version of libX11 will be linked at runtime.

I'd prefer the conservative "maybe leaking" one at this stage as I
said first in
http://lists.gnu.org/archive/html/emacs-devel/2009-05/msg00263.html .

The third non-crashing non-hideous way would be to associate the
created database before any call to XGetDefault so it may not set the
XlibDisplayDfltRMDB flag.  That will require reordering in the display
initialization and we can try it after the release.
