• DispatchQueue

  DispatchQueue is a simple way to serialize jobs.
  It was done for crawling things, but could be used in any case that you need to do more than one work at a time.

  COMPATIBILITY

  Check build status to see support in different platforms

  

  USAGE

  [1,2,3].threaded_each{|i|
    sleep 4-i
    puts i}

  3
  2
  1

  [1,2,3].threaded_map{|i| sleep 4-i ; i } #=> [3,2,1]

  my_work_queue = DispatchQueue.new(lambda{ sleep 3 ; 5},  lambda{ 10 })my_work_queue.sort #=> [5, 10]

  DQ[ lambda{ sleep 5 ; 3} , Proc.new{ sleep 6; 2 } ].sort #=> [2,3]
