  Modified files:
    sys/kern             tty.c 
  Log:
  Be more careful with sched_lock in the SIGINFO handler.  Specifically, do
  not hold sched_lock while calling ttyprintf().  If we are on a serial
  console, then ttyprintf() will end up getting the sio lock, resulting in
  a lock order violation.
