<i>As for robustness, if doing X will cause a crash and your code does X, then you will just have a bunch of crashing processes rather than just one. How is that better? Wouldn't the real solution be to either stop doing X or fix X so that it doesn't cause a crash?</i> Sure, but bug-free code doesn't exist and not all crashes happen 100% of the time. If you have a difficult to track down crash bug that happens for some mysterious reason once every 100,000 requests... Would you rather have that resulting in the entire server blowing up or one request-session blowing up?
