Review comment:
Here `err` is an error after timeout or cancelation (in that case
`cmd.Run()` doesn't finish completely).
If `err` is `nil` it means that `cmd.Run()` finishes completely.
In case of `cmd.Run()` finishes and it doesn't have any error (there is no
any typos into the code for example) then `ok` is `true` and we need to call
`processSuccess()` method. However if code contains some typos then
`compileCmd.Run()` will return `err` and write error description to
`compileCmd.stdErr`. In that case `ok` is `false` and we need to call
`processError()` method.
