- Add dev-dependencies for divan and uucore with benchmark features to Cargo.toml - Include a new benchmark harness for timeout_bench - Optimize signal lookups using OnceLock for KILL and CONT signals to avoid repeated computations - Introduce preserved_child_exit function for accurate exit status handling - Update send_signal and wait_or_kill_process for improved efficiency and correctness - Update Cargo.lock with new dependency codspeed-divan-compat This enhances performance testing capabilities and reduces overhead in signal operations for the timeout utility.

… unused test - Reduced sleep time in "long-sleep" mode from 2s to 200ms for faster execution - Shortened timeout values in quick_exit and enforced benchmarks from 0.1s/0.05s to 0.02s - Removed timeout_kill_after benchmark to streamline test suite and improve performance
Removed unnecessary blank lines after the bench_timeout_with_mode call in src/uu/timeout/benches/timeout_bench.rs to improve code readability and consistency.

Whats the reason that this PR is combined? Would it be possible to split the benchmarking and the timeout enhancements? |
