 It might or might not be related to kern/41417.  I think there are
 actually two bugs here per the two different failure modes reported:
 
   a) an error branch locking error, where a vnode is not unlocked
      properly
   b) a reference couting bug which causes use-after-free
      (the test case vnodes are recycled immediately due to them
      having a 0 link count)
 
 There might one or more cases of "a", and 41417 might be one of them.
