  Now that Giant is acquired in uprintf() and tprintf(), the caller no
  longer leads to acquire Giant unless it also holds another mutex that
  would generate a lock order reversal when calling into these functions.
  Specifically not backed out is the acquisition of Giant in nfs_socket.c
  and rpcclnt.c, where local mutexes are held and would otherwise violate
  the lock order with Giant.
  
  This aligns this code more with the eventual locking of ttys.
