With go1.9beta1 (Linux / amd64) I noticed an extra file descriptor that I
cannot explain.
A simple example is after calling ioutil.ReadDir().
package main
import (
"fmt"
"io/ioutil"
)
func main() {
_, err := ioutil.ReadDir(".")
if err != nil {
panic(err)
}
fmt.Scanln()
}
sudo lsof -p `pidof fd-go1.9beta1`
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
fd-go1.9b 3698 peter cwd DIR 8,2 4096 23596911 /home/peter/go/
src/fd
fd-go1.9b 3698 peter rtd DIR 8,2 4096 2 /
fd-go1.9b 3698 peter txt REG 8,2 1964089 23596832 /home/peter/go/
src/fd/fd-go1.9beta1
fd-go1.9b 3698 peter 0u CHR 136,1 0t0 4 /dev/pts/1

fd-go1.9b 3698 peter 4u a_inode 0,12 0 9667 [eventpoll]
FD #4 doesn't show up with go1.8.3. Is this expected, a bug or something
else?
Thanks!
