    kernel - Attempt to make procfs MPSAFE
    
    * pfs_pfind() now acquires the p->p_token in addition to its PHOLD().
    
    * Replace PRELE()'s with pfs_pdone() which releases the token along
      with PRELE()
    
    * Double-check the validity of nch's passed to cache_fullpath().  This
      probably still needs work.
