Hi Derek:

Thanks for the input.  

I know that stderr is duplicated, so that's not a problem.  I long
suspected terminal problems, but I know that openpty is setting
the term correctly from when I was mucking around with whether or
not I wanted the terminal running in canonical mode.

I changed out the call to setsid, but that didn't change anything.
I've also tried using tcsetpgrp() and calling fork() and exit() to 
make the shell an orphaned process -- neither of which seemed to
do any good.

I used to suspect that the pty wasn't set up correctly and I
eventually ended up duplicating the termios structure bit by
bit and setting the pty to the characteristics that a pty from
ssh gets, but that didn't do the trick either.  That suggests
to me that the problem isn't terminal related, but rather that
it's related to the setup of the child process.  Maybe this is
the fault of an environment variable?
