When performing a noop sync, we don't need the rayon threadpool, yet we pay for its initialization:  Be making the initialization lazy, we avoid that cost:  This code runs every time before user code in `uv run`. This means that before calling rayon, one now needs to call `LazyLock::force(&RAYON_INITIALIZE);`. Performance mode (CPU 0 is a perf core): ``` $ taskset -c 0 hyperfine --warmup 5 -N "/home/konsti/projects/uv/uv-main sync" "/home/konsti/projects/uv/target/profiling/uv sync" Benchmark 1: /home/konsti/projects/uv/uv-main sync Time (mean ± σ): 4.5 ms ± 0.1 ms [User: 2.7 ms, System: 1.8 ms] Range (min … max): 4.4 ms … 6.4 ms 640 runs Warning: Statistical outliers were detected. Consider re-running this benchmark on a quiet system without any interferences from other programs. It might help to use the '--warmup' or '--prepare' options.
