  Log:
  MFC revision 1.290
  
  Hopefully close up race between the TTY (t_session) subsystem and exit(2)

  Back out one of the Giant removals from revision 1.272. Giant was not here to
  protect the vnode, it was present to synchronize access to TTY session
  information between exit(2) and the TTY code. While we are here, note that
  Giant is required for TTY protection.
