Yes I originally wrote it for exactly this such a scenario.

This is not for you if you cannot live with any chance of a false positive, even an extremely small one. Note that even in most cases a false positive is acceptable if the chance of a false positive is less then the chance of a hardware error.

Not that just because it is probabilistic does not mean its not useful in many cases. The default setup with 1mil entrie memory and 1/1mil chance false positive chance will run at ~8M mem usage. This is a quite an acceptable trade off in many cases.
