Let me add one more fact.

On SONY NWS3860, the largest X application under /usr/bin/X11 is mwm.

If you run mwm, xdm and as many xterms as you want,

	text	data	bss	dec	hex
	1007616	192512	27168	1227296	12ba20	/usr/bin/X11/mwm
	413696	86016	27792	527504	80c90	/usr/bin/X11/xdm
	585728	139264	39376	764368	ba9d0	/usr/bin/X11/xterm

still, total text size is below 2MB.

So, shared library is NO solution even to reduce memory consumption of X11.
