    Refactoring and reorganisation of the scheduler · 99df892c

    Change the way we look for work in the scheduler.  Previously,
    checking to see whether there was anything to do was a
    non-side-effecting operation, but this has changed now that we do
    work-stealing.  This lead to a refactoring of the inner loop of the
    scheduler.
    
    Also, lots of cleanup in the new work-stealing code, but no functional
    changes.
    
    One new statistic is added to the +RTS -s output:
    
      SPARKS: 1430 (2 converted, 1427 pruned)
    
    lets you know something about the use of `par` in the program.
