BAD idea, it's occasionally useful to have init put a getty on the slave
side of one of the higher pty numbers, some other non-aware program can
then be told to open the master side. An example is to provide DOSEMU
with a simulated serial line to the linux machine.

If the open returned EIO the getty would die then be respawned repeatedly,
init gives up PDQ.
