Hi,

if I try to run about 100 concurrent v8 instances, this error occurs.
It also occurs eventually if I run 10 concurrent instances multiple times.

Here is the code to reproduce:
https://github.com/i5heu/distribution-game/tree/e8e7a5146a1bad3c132d48c0744a410ecdc15421

run in cloned repository on commit level e8e7a5146a1bad3c132d48c0744a410ecdc15421 :

npm i
npm run build
cd backend
go run .

go with your browser to localhost:3333 and click on "Run" on the right half of the screen.

I'm having the same issue if I try to create around 500+ contexts in goroutines (less than that seems to work fine).

Sample code creating ctx in loop 
wg := sync.WaitGroup{}
for _, currentContent := range allContent {
	wg.Add(1)
	go func(currentContent content, wg *sync.WaitGroup) error {
		defer wg.Done()
		ssrCtx, err := createSSRCtx()
		if err != nil {
			return fmt.Errorf("\nCan't create SSR Context for %s %w", currentContent.contentFilepath, err)
		}

                doSomething(ssrCtx)
			
		ssrCtx.Close()
		return nil
	}(currentContent, &wg)
}
wg.Wait()

The createSSRCtx() just creates new ctx and loads some scripts like:

func createSSRCtx() (*v8go.Context, error) {
	ssrCtx := v8go.NewContext(nil)
        // Load some scripts (abbreviated)
        ssrBytes, _ := afero.ReadFile(ssrFS, somepath)
        ssrCtx.RunScript(string(ssrBytes), "create_ssr")
        return ssrCtx, nil
}
