Why can't I seem to run perl attached to the slave side of a psuedo tty?
I have a program that creates a ptty, and fork/execs a perl script with
its stdin, stdout, and stderr duped to the slave half of the ptty.
My wish is to make the perl script think its getting input from stdin
and producing output on stdout, when its this parent process that is
doing the work.

Perl seems to be doing something to its stdin and stdout file descriptors
that prevents such control.  Anyone done this sort of thing before?  How?
