Many ssh <defunct> then using library.

[neodiz]

Good afternoon. I think I found a problem in the library, a large number of child processes are not closed. Here is my example

`func ansible() error { fmt.Println("test") ansiblePlaybookConnectionOptions := &options.AnsibleConnectionOptions{ User: "inurmuhametov", SSHExtraArgs: "-o ControlPersist=360s", SCPExtraArgs: "-o ControlPersist=360s", SFTPExtraArgs: "-o ControlPersist=360s", }

ansiblePlaybookOptions := &playbook.AnsiblePlaybookOptions{
	Inventory:  "<server>,",
	VerboseVVVV:true,
}

playbook := &playbook.AnsiblePlaybookCmd{
	Playbooks:         []string{
		"/tmp/performance.yml"},
	ConnectionOptions: ansiblePlaybookConnectionOptions,
	Options:           ansiblePlaybookOptions,
}

err := playbook.Run(context.TODO())
if err !=nil {
	playbook = nil
	return err
}
playbook = nil
return nil

} func main() {

for ; ;  {
	ansible()
	time.Sleep(5 * time.Minute)
}

}`
