The cessna model is about as vanilla OpenGL 1.x as you can get. It's been
part of the OSG data for over a decade without problems.

For an OSG app to lock the whole machine up suggests a driver issue as the
OSG code itself is all just straight forward C++, there aren't any clever
hacks.  On the OpenGL side we just pass data along to OpenGL and let the
driver do what it needs to do.  The drivers themselves are low level with
direct control of hardware and collaborate with the OS at low level so has
lots of potential for bugs to cause major failures.
