title: Jenkins - Running instances of single build concurrently
body: <p>I'd like to be able to run several builds of the same Jenkins job simultaneously.</p>
  
  <p>Example:</p>
  
  <ol>
  <li>Build [*jenkins_job_1*]: calls an ant script with parameter 'A'  </li>
  <li>Build [*jenkins_job_1*]: calls an ant script with parameter 'B'  </li>
  <li>repeat as necessary</li>
  <li>each instance of the job runs simultaneously, rather than through a queue.  </li>
  </ol>
  
  <p>The reason I'd like to do this is to avoid having to create several jobs that are nearly identical, all of which would need to be maintained.</p>
  
  <p>Is there a way to do this, or maybe another solution (ie — dynamically create a job from a base job and remove it after it's finished)?</p>
