Than any your users use perhaps - we have had users with applications that ran
out, especially CAD/CAM type applications. Remember that older toolkits did
a lot more server side than GTK & Qt today, and some did things like creating
a new Window id for every widget.

While I've not extracted the change into a patch that could be easily ported/applied to Xorg, the code to the Solaris Xsun fork of the X11R6.*
server fork has since been published if someone else wants to try.

The code to the entire server is published at:
http://dlc.sun.com/osol/x/downloads/openXsun/

The command-line selectable 128/1024 clients code changes should be in these
files (and possibly more, I've not searched, just referring to our original
code changes - and obviously not all these apply to X11R7.x/Xorg 1.x):
