MFC: It turns out that the following:
       close(1);
       close(2);
       x = open(ctermid(NULL), O_RDWR|O_NONBLOCK);
       close(0)
     on a tty causes select() to return an exception for descriptor x !
     This is the case in RELENG_2_2, but not in 2.2.2.  I'm not sure why.
     Instead of doing the x=open() and close(0), we just do x=0 now.
     Problem pointed out by: Greg Lehey <grog@lemis.com>
