title: What does "Computing additional info" mean?
body: <p>Eclipse Helios periodically starts running a job which displays "Computing additional info". During this time, Eclipse is very sluggish, bordering on unusable. What does this job do? Can I shut it off?</p>
  
  <p>I just hope that someone in the JDT team comes to sense and gets rid of it, make it go faster, or at the very least change it to something meaningful.</p>
