title: Dedicate Tomcat threads to servlet
body: <p>Is there anyway to configure tomcat to reserve threads to a specific servlet or webservice?
  I understand this could probably be done programatically in a servlet filter.</p>
  
  <p>So suppose I go with the default configuration of 250 serving threads, but I want 20 of them to be reserved for a specific servlet/webservice?</p>
  
  <p>Maybe this is obviously impossible -  if so could someone please explain why?</p>
  
  <p>Im using tomcat 6.</p>
