Keep a batch-level deadline in the fallback path.
When GNU timeout is unavailable, this branch starts Bun without the configured ${BATCH_TIMEOUT_SECONDS}s process deadline. A stalled Bun process that is not an individual test timeout can then hold the CI shard indefinitely.
Use a portable watchdog that terminates the Bun process or process group after BATCH_TIMEOUT_SECONDS, or fail explicitly when no bounded fallback is available. Do not bypass the batch deadline.
As per coding guidelines: “Use explicit paths, deterministic inputs, bounded resource use, and actionable failures.” As per path instructions: flag changes that weaken CI gating.

… batch deadline without GNU timeout The fallback ran Bun with no batch deadline when GNU timeout was missing, so a wedged batch on macOS ran until the job's wall clock. It now keeps the same contract as timeout --signal=TERM --kill-after=GRACE SECONDS: - The batch runs through perl setpgrp as the leader of its own process group, as it does under GNU timeout. - A watchdog sends TERM (then CONT) to the group at the deadline, waits up to the grace period for the group to empty, then sends KILL. Its output goes to /dev/null so it never holds the tee pipe. - A timed-out batch reports 124, or 137 when the batch itself needed KILL, matching GNU timeout; INT, TERM and HUP are forwarded to the group. - Without GNU timeout and without perl the runner still exits 69. dev already replaced mapfile, so the merge keeps dev's loop and its PARALLEL_ARG. macOS sort accepts -z, so the NUL-delimited listing stays. Tests run the real runner without GNU timeout: a clean run stays green, a hung batch whose child ignores TERM exits 124 with the child gone, and a batch that ignores TERM itself exits 137.

Report the macOS validation status for the portable deadline.
The tests force the non-GNU branch with timeoutTool: "non-gnu", but they do not execute it on macOS. The fallback depends on macOS behavior for setpgrp, negative-process-group kill -0, and the trapped-signal wait loop. Add the macOS result to the PR, or state explicitly that macOS validation was not executed. Include whether the hang cases return 124/137 and remove a TERM-ignoring child.

Maintainer update: pushed The review was right that the fallback ran Bun with no batch deadline, so a wedged batch on a Mac would run until someone killed it. Without GNU
On the other review points: Local checks were not run for this push; hosted Cross-platform CI on Follow-up from an independent review of the new function, not pushed because this PR was merged at this head: if the runner itself receives TERM (for example a whole-group kill) while a batch that ignores TERM is running, the wrapper forwards TERM and the watchdog exits on the same signal, so nothing escalates to KILL and the pipeline can hang.
