Issue with sass-embedded when the system runs out of resources

[VioletFlare]

Bug report

Prior to this bug report, I've opened an issue on the sass-embedded board and it was suggested that it might be related to how sass-loader handles sass-embedded.

https://github.com/sass/embedded-host-node/issues/296#issuecomment-2103359060

I am using sass-embedded alongside sass-loader in my webpack config. I've noticed, that when running out of memory and physical memory the dart processes throws errors and stop.

Actual Behavior

Webpack doesn't crash and exit, but there are dart errors printed out and the compilation stops.

webpack --config webpack.configs.dev.js --watch

Expected Behavior

It was suggested that it might be due to sass-loader spawning many instances of sass-embedded, maybe sass-loader should be more conservative when using resources?

How Do We Reproduce?

This is my sass-loader config:

					{
						loader: 'sass-loader',
						options: {
							sassOptions: {
								sourceMap: true,
								includePaths: [path.resolve(__dirname, 'Develop', 'Styles'), path.resolve(__dirname, 'WebComponents')],
							},
							implementation: require('sass-embedded')
						}
					}

I run two sass-loader instances in parallel to compile two sections of a pretty big codebase of sass.

To reproduce this problem it is necessary to exceed the system memory, in my case I went above 6-8 GB out of 16 GB. It is also necessary to not have much physical memory available. I had something near 500-250 MB.
