In the S5R3.1 source, that message comes if "pg" can't do an "freopen"
on "stdout" with "/dev/tty".  I suspect this dates back to S5R2. 
Perhaps "ksh" is setting things up so that the child process doesn't
have a controlling tty? Seems more likely than some problem with some
file getting improperly closed....
