  SVN rev 198307 on 2009-10-20 21:29:46Z by thompsa
  
  Change from CAM_TID_INVALID to CAM_SEL_TIMEOUT error code when the usb device
  has been yanked, this works around a cam recounting bug when
  CAM_DEV_UNCONFIGURED is set late in the detach. In certain conditions the
  reference to the XPT device would not be released which would cause the usb
  explore thread to sleep forever on "simfree", preventing any new usb devices to
  be found/ejected on the bus.
  
  This is intended to be a quick workaround to the problem without touching CAM
  so it can be merged to 8.0.
