[Bf-cycles] still memory problem with cuLaunch on GTX780Ti 3GB with empty scene

We run into this on Windows a bunch, disabling / enabling persistent images
seems to fix it for us. It is usually caused (for us at least) by either
long animation renders (memory leak somewhere which I haven't been able to
hunt down), overheating GPUs or RAM problems on the CPU.
However, if it is rendering via commandline and its a long animation...
sometime can be annoying that one computer outputs all these black frames
because of a crash. Would be worthwhile to implement some sort of 'if
cycles crashes dont save anything out' type flag for commandline rendering.
