  Log:
  Push things closer to path failover by implementing loop down and
  gone device timers and zombie state entries. There are tunables
  that can be used to select a number of parameters.
  
  loop_down_limit - how long to wait for loop to come back up before
  declaring
  all devices dead (default 300 seconds)
  
  gone_device_time- how long to wait for a device that has appeared
  to leave the loop or fabric to reappear (default 30 seconds)
  
  Internal tunables include (which should be externalized):
  
  quick_boot_time- how long to wait when booting for loop to come up
  
  change_is_bad- whether or not to accept devices with the same
  WWNN/WWPN that reappear at a different PortID as being the 'same'
  device.
  
  Keen students of some of the subtle issues here will ask how
  one can keep devices from being re-accepted at all (the answer
  is to set a gone_device_time to zero- that effectively would
  be the same thing).
