[Bug]: ADetailer locks available CPU threads to 8 after running the script once

[ChiNoel-osu]

Describe the bug

sd-webui is ran in CPU only mode:

export COMMANDLINE_ARGS="--no-download-sd-model --listen --enable-console-prompts --enable-insecure-extension-access --use-cpu all --precision autocast --no-half --skip-torch-cuda-test"
export CUDA_VISIBLE_DEVICES="-1"
export OMP_NUM_THREADS=24
export MKL_NUM_THREADS=24

Inference without enabling the ADetailer script will use 24 threads every time.

When ADetailer script is enabled in this session, the first pass (where it generates with original prompts and settings) of the first generated image will use 24 threads, the "ADetailer" pass (where it masks the generated image and inpaints it) will only use 8 threads. All subsequent inferences will only use 8 threads from now on, even if I disable ADetailer.

Steps to reproduce

0. Have a CPU that has more than 8 threads
1. Launch webui in CPU only mode
2. Generate any image w/ ADetailer script
3. Observe the CPU usage during each pass

This is a problem I never imagined. Please let me know what hardware and software version you're using and I'll give it a try.

Also, since there was a supply chain attack on the ultralytics package, please make sure you're not using version 8.3.41 of ultralytics.

[ChiNoel-osu]

Using the latest version of both SDWebUI (82a973c) and adetailer (v24.11.1).
The CPU is an Intel Xeon w7-3455 (24C48T), but I think any CPU with more than 8 cores should be able to reproduce this problem.

ultralytics 8.3.19
