use a timeout+exit() to avoid slow inputs. Libfuzzer has its own timer that it uses to catch slow inputs, however these timeouts are usually seconds-minutes long: more than enough to bog-down the fuzzing process. However, I found that slow inputs often attempt to fill overly large DMA requests. Thus, we can mitigate most timeouts by setting a cap on the total number of DMA bytes written by an input.
