Local "DOS" against the NVidia Linux driver

Because of a bug, I found out that looping on glClear causes very painful results with the NVidia Linux driver. It makes the desktop unusable, updating only every 2 seconds, and no events will reach any program. Only way to get out of it is to switch to a tty, then events seem to be transmitted, and the program will be exited. X crashed once when I switched to a tty, tho. Try out on your own risk.

EDIT: Warning: Seems that I didn't fix the bug in the program, so I got into the same situation again (however, my program runs a few gl statements in between every glClear) and the machine became so unresponsive that I couldn't even switch to a tty (had no second computer to ssh in with, that would likely have solved it). I repeat, run it at your own risk.

Here's a test-case:

#include <sdl.h>
#include <gl.h>

int main(int argc, char *argv[])
{
     SDL_Surface *screen;
     int i = 0;

     SDL_Init(SDL_INIT_VIDEO);

     screen = SDL_SetVideoMode( 640, 480, 0, SDL_OPENGL | SDL_GL_DOUBLEBUFFER );

     glMatrixMode(GL_MODELVIEW);

     while (1)
     {
             glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT | GL_STENCIL_BUFFER_BIT);
     }
     SDL_Quit();

     return 0;
}

Note that I am running a rather old version of the NVidia Linux driver, 173.14.09, they could very well have fixed this in newer versions.
