    tdf#38837 Reduce power consumption by minimizing idle timers
    
    Based on profiling, Writer's most CPU consuming idle event was
    document statistics calculation.
    This patch stops the idle timer once statistics has been updated.
    Subsequent profiling shows a sharp decline in CPU usage.
    
    Modifications to the document should initiate statistics update.
