Description Brent Fulgham 2021-05-06 14:21:56 PDT 
We allow read and write access to /dev/zero and /dev/null in all of our sandboxes, except for Network process on iOS. This is a mistake, and leads to spurious sandbox violation reports. We should allow this to avoid generating these reports, and because these devices are frequently used in low-level programming.
