A bare `9>&-` on the sleep line reads as removable redirection noise. It is not: it is what stops an orphaned `sleep` from holding the per-host single-instance flock (fd 9, opened at `exec 9>"$lock"`) after the detector parent dies, which would leave a lock no replacement instance can ever acquire. The comment also states the half that makes the fix safe — `9>&-` closes ONLY the child's copy, so the parent detector's lock is untouched. Comment-only. Verified: stripping comment lines from this file yields output byte-identical to the same operation on the reviewed head60f8caf4d8(397 non-comment lines both sides), so no executable line changed. `bash -n` and `git diff --check` pass. The file is now 576 lines, not 572, and the sole sleep site moves from line 532 to 536 — rev-974's line derivations need recomputing at the new sha. Requested by rev-974 in the CHANGES-REQUIRED verdict on #993 (comment 19818), which bound to head60f8caf4d8. That verdict is void at this new sha by the standing verdict-at-head rule; re-verdict required before merge.
