sleep 4-i
puts i

[1,2,3].threaded_map{|i| sleep 4-i ; i } #=> [3,2,1]- The explicit way:
my_work_queue = DispatchQueue.new(lambda{ sleep 3 ; 5}, lambda{ 10 })
my_work_queue.sort #=> [5, 10]- The implicit way:
DQ[ lambda{ sleep 5 ; 3} , Proc.new{ sleep 6; 2 } ].sort #=> [2,3]- 1.1.0 Create [].threaded_each [].threaded_map (2011/09/22)
