I do X development, I must disagree. Most X screwups result in either a return to text mode and a logged signal catch, or at least the ability to log back in and clean up/reboot nicely. Very important on server systems. The work Jon Smirl is doing is aimed at significantly reducing the number of occurences where such clean up/reboot is required.
