Yes.  A high percentage of all server crash reports we receive happen
when xscreensaver is running.

Especially when the OpenGL screenhacks are used.

This is probably because the graphics engine is in a bad state and the
the driver-specific LeaveVT() logic doesn't succeed in unscrewing it.

All I can suggest as a workaround is to configure xscreensaver to not
use the screenhacks that seem to cause trouble.
