I have never personally had any bottles explode on me, and I have been re-using commercial bottles for years for bottle-conditioning. In fact, the only time I have ever even really thought about exploding bottles is when I have made sodas with the kids.
For beer, I have stopped using 12oz bottles though, and switched to the 22oz bottles, which are considerably more heavy duty than 12oz bottles. So my thought is, if you are really worried about it, switch to 22oz bottles.
One might venture to say (depending on the beer style - of course), if you end up with exploding bottles when brewing beer, you may want to take a look at your process (bottling too soon, too much priming sugar etc). You could always take a play from the soda maker's handbook, and refridgerate your bottles once they hit an acceptable level of carbonation - although you will slow to a crawl any further conditioning - if needed.
