    tmpfs - Fix lost vnode reference due to race
    
    * Under certain race conditions when a vget() fails and must
      retry, the vnode is not completely unwound and an extra ref
      is left on it.
    
    * Can cause files in tmpfs to build-up and eat space even if deleted.
    
    * Relatively rare.
