What did you do?
The following code shows that the chain of goroutines A and B remains and intuitively I think they can be removed from the scheduler. Is this necessary to remove them or any reason that removing is not a good choice or that's just not a deal?
package main
import (
"fmt"
"runtime"
"time"
)
func B() {
select {}
}
func A() {
B()
}
func main() {
go A()
for i := 0; i < 20; i++ {
time.Sleep(1 * time.Second)
fmt.Println(runtime.NumGoroutine())
}
}What did you expect to see?
