Copies of its container value refer to the same underlying allocation, so passing the container into several jobs does not give each job an independent result buffer. [2][3]\n\nMark a job field `[ReadOnly]` when that job only reads it. Multiple readers can then share the input without falsely declaring write access. A producer writing an array and a consumer reading it need an explicit dependency. The main thread must also respect pending access; it is not exempt from the container's safety rules.
