Overview

Writes to fd 2 and then either dies the way a C library does — exit() with no Ruby exception, so there is no worker.crashed line and nothing on the connection — or returns normally, which is the warning a cell deliberately does not report. noise: goes out before text:, so a test can ask which end of an oversized transcript was kept.
