title: ProducerTemplate is there supposed to be only one instance
body: <p>We are using Spring and Camel in our web application.  In one of our controllers we are using the ProducerTemplate to send a message on a route and now I want to add another controller that will send a message down a separate route.  I an trying to understand if we are only suppose to have one ProducerTemplate for the whole application?</p>
  
  <p>I ask this because I got a little confused after reading <a href="http://camel.apache.org/why-does-camel-use-too-many-threads-with-producertemplate.html" rel="nofollow">this</a>.</p>
