  // number of GC threads (ParallelGCThreads).  The job might be divided
  // into a number of tasks greater than the number of GC threads for
  // load balancing (i.e., over partitioning).  The last task to be
  // executed by a GC thread in a job is a work stealing task.  A
  // GC  thread that gets a work stealing task continues to execute
! // that task until the job is done.  In the static number of GC theads
  // case, tasks are added to a queue (FIFO).  The work stealing tasks are
  // the last to be added.  Once the tasks are added, the GC threads grab
  // a task and go.  A single thread can do all the non-work stealing tasks
  // and then execute a work stealing and wait for all the other GC threads
  // to execute their work stealing task.
