I'm of two minds about whether it's a good idea to do this, though. I have done it once in the past, out of frustration at trying to support a particularly failure-prone application, and can confirm it was a useful thing to do at the time. I haven't done it since, though, and eventually ripped it back out once I got the app wrestled back to a happy place. The problem is, it lets you get away with not thinking very hard about your application's failure modes. So my sense was that, over the long run, the cure is worse than the disease.
