	Uh, that's not a problem I'd worry about with CO2 generation.
In brewing, the sediment (which has a specific name I can't remember
right now) can cause off-flavors and odors if the ferment is left on
it too long. With beer, you're talking about weeks. With wine, you're
talking about months. Also, beer and wine has a lot more in it than
water, sugar, and yeast -- proteins, longer sugars, starches, and 
all the chemicals the plants had in their fruits.

	You can't avoid some of the yeast dying; it happens, for
whatever reason. As long as CO2 is coming off the mixture, there's
healthy yeast living, eating, and reproducing in there. When the
fermentation stops, it means that either the food supply's been
exhausted or the waste (alcohol) has reached an unhealthy level for
the yeast.
