The PSNR/stddev calculation certainly wouldn't work right with that.
But if it is necessay to reduce the time for make test it would be
possible, though personally a better idea would be to introduce either
a slowtest or fasttest target, because if we already start to limit
what we test at the current level we'll never reach really significant
code coverage.
