  Log:
  SVN rev 189029 on 2009-02-25 11:18:18Z by rwatson
  
  Correct a deadlock and a rtentry leak in rt_check():
  
  - In the event that a gateway route has to be looked up, drop the lock
    on 'rt' before reacquiring it 'rt0' in order to avoid deadlock.
  
  - In the event the original route has evaporated or is no longer up
    after the gateway route lookup, call RTFREE() on the gateway route
    before retrying.
  
  This is a potential errata candidate patch.
