Having discussed this a bit more with Marc, it appears that the
XSetCloseDownMode() is the crucial call here. It can be used in each
non-GUI forked process to stop that process from tearing down the X
resources when it exits.

It would be useful if this call were exported from Gtk (as
gtk_cleanup_on_exit, or somesuch.)
