Shared memory and images on remote X server

[Greg Badros <gjb cs washington edu>]

I'm having problems using guile-gtk from within Scwm displaying on a
remote X server.  Gtk seems to want to use the shared memory and X
shared memory extensions despite using a remote display.  Is there any
(run-time) way to turn off the shared memory extension?  Shouldn't gtk
automatically get this right when the DISPLAY is remote?

Thanks,
