      Description

      It's easy to grab the number of millis spent in GC (see JvmMetrics for example). Exposing these as task counters would be handy - occasionally I've seen user jobs where long GC pauses cause big "unexplainable" performance problems, and a large counter would make it obvious to the user what's going on.
