Show HN: Corral – Kill every command your agent starts

Corral is a utility designed to run commands with a time limit, ensuring that no processes started by the command remain alive upon its return. It verifies this before exiting, returning code 120 if it cannot prove termination. Tests show Corral successfully terminated all processes across various scenarios, including those that fork children, start daemons, or ignore SIGTERM. For example, it stopped F9 at its 64 MiB limit in 0.12 s. In contrast, a timeout utility from uutils coreutils 0.8.0 sometimes left processes alive.
