    bioq - Add a sysctl kern.bioq_barrier to control bioqdisksort()'s sorting.
    
    Control how well sorted we want bioqdisksort() to be.  The value specified
    in kern.bioq_barrier is the number of bio's that will be sorted until a
    barrier is inserted, starting a new set.  The default value is 16.
    
    This allows testing filesystem throughput under varying conditions.
