You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: timer_set.rb
    path of file: ./repos/concurrent-ruby/lib/concurrent-ruby/concurrent/executor
    
    the code of the file until where you have to start completion: require 'concurrent/scheduled_task'
require 'concurrent/atomic/event'
require 'concurrent/collection/non_concurrent_priority_queue'
require 'concurrent/executor/executor_service
    
    def ns_post_task(task)
      return false unless ns_running?
      ns_reset_if_forked
      if (task.initial_delay) <= 0.01
        task.executor.post { task.process_task }
      else
        @queue.push(task)
        # only post the process method when the queue is empty
        @timer_executor.post(&method(:process_tasks)) if @queue.length == 1
        @condition.set
      end
