SublimeLinter is linting during typing, possible fix

When i'm typing fast, sublime starts stuttering. I see in task manager that php is linting during typing. I've set a delay to 2 seconds. So it should only linting after typing. Is there a reason why fast delayed queues are not allowed? Commenting these 2 lines fix the stuttering issues and php will be called only once and not several times.
