Slow safetensors loading

I'm pretty sure this is probably entirely a Comfy UI thing, but maybe still worth asking here.

Slow safetensors loading was fixed in A1111 with a specific option (Disable memmapping for loading .safetensors files.). It seems to mostly only happen with 64GB of RAM or in other specific cases, due to #justwindowsthings with Windows memory management.

AUTOMATIC1111/stable-diffusion-webui#11216

I'm not sure if Comfy UI has an equivalent setting. I've tried a couple of command arguments but they didn't really work. There might be a specific option to change somewhere, but I don't really use Comfy outside of Krita AI Diffusion. It's not that bad for SD 1.5, but SDXL checkpoints take about 2 minutes to load, while they load on average in 45 seconds in A1111.

So I found the fix

comfyanonymous/ComfyUI#1992 (comment)

Why it hasn't been added at least as an option on Comfy, who knows #justcomfythings

This DOES break other models from loading, like ControlNet and upscalers, so I guess I get now why it's not on by default.
