Why doesn't this code return a “deadlock” error?

Question

package main

import (
    \"fmt\"
    \"net/http\"
)

func Extract(url string) ([]string, error) {
    http.Get(url)

    var links []string
    return links, nil
}         


        

Answer 1

Importing the net package starts background polling Goroutines that effectively disable the deadlock detector.
