[SDL] Wierd semi-freeze

[Brad]

I've written a game that uses SDL and OpenGL, and under Linux every so 
often it'll freeze. Not just the game but *everything* freezes. The 
little diagnostic LEDs on my motherboard, which normally flash all sorts 
of numbers when Linux is running stop flashing. It's frozen. But after a 
few minutes everything suddenly starts working again, like nothing had 
happened.

I have no idea what's causing this. I'm using SDL 1.2.5, SDL_mixer, and 
SDL_image. My graphics card is a GeForce 2 GTS with latest drivers.
