> For validators, we start a single goroutine for validateFunc in which we loop through all validators synchronously. 
>  
> {code:java}
> go validateFunc(successChannel, errorChannel, valResChannel)
> // Validate returns the function that applies all validators of executor
> func (ex *Executor) Validate() func(chan bool, chan error) {
>     return func(doneCh chan bool, errCh chan error) {
>         for _, validator := range ex.validators {
>             err := validator.Validator(validator.Args...)
>             if err != nil {
>                 errCh <- err
>                 doneCh <- false
>                 return
>             }
>         }
>         doneCh <- true
>     }
> }
> {code}
>  
> Instead of that, we should start goroutines for each loop step. And control results for each validator with separate channels.
