  SYNOPSIS
    enumerable = %w( a b c d )
    enumerable.threadify(2){ 'process this block using two worker threads' }

  DESCRIPTION
    threadify.rb makes it stupid easy to process a bunch of data using 'n'
    worker threads

  INSTALL
    gem install threadify

  URI
    http://rubyforge.org/projects/codeforpeople

  SAMPLES
    <%= samples %>

  HISTORY
    1.0.0
      - adjust threadify to yield objects exactly like Enumerable#each

    0.0.3
      - added ability to short-circuit the parallel processing, a.k.a to 'break'
        from threadify

    0.0.2
      - don't use thread.exit, just let the thread die naturally
      - add version to Threadify module
      - comments ;-)
