  Log:
  Switch from bioq_insert_tail() to bioqdisksort().  When the kernel is
  juggling hundreds of I/O requests the on-disk controllers, which have limited
  queue sizes, are unable to completely optimize the accesses.
  
  This seems to make a pretty big difference on the twe device I tested with
  when running blogbench on HAMMER, which can approach 1000 simultaniously
  queued I/O's.
