Some notes about the gist:

• Calling "sync" creates an array to keep track of return values from any asynchronous operation.

• The "resume" method is called in your generator code and its return value is passed as the callback to your asynchronous operation. Calling "resume" causes a counter to increment, letting your "sync" method know how many asynchronous operations are in flight.

• The return value of "resume" is a function that causes the result of the asynchronous operation to be placed into the data structure in #1. Immediately after doing this assignment, we check to see if there are any outstanding asynchronous operations. If not, we resume the generator with either an (ordered) array containing the results of our asynchronous operations or (in the event of only one operation having been fired off)

The important thing to note is that both asynchronous operations have been fired off before yielding. Each callback (passed to these asynchronous calls) is the return value from the call to "resume" -

Add union_hack.rb to your project, for example at lib folder and ensure you're loading it on your application.rb file:

    # You'll need to add something like that
    config.autoload_paths += %W(#{config.root}/lib)

Then extend your favourite model with the module and you'll be able to do unions with unique records, sorted by any fields and limited in number of records (see my_timeline_method):

    class Profile < ActiveRecord::Base
      extend UnionHack
