    kernel - Fix getpid() issue in vfork() when threaded
    
    * upmap->invfork was a 0 or 1, but in a threaded program it is possible
      for multiple threads to be in vfork() at the same time.  Change invfork
      to a count.
    
    * Fixes improper getpid() return when concurrent vfork()s are occuring in
      a threaded program.
