I came across an old bug filed in debian about script being redirected
from a file misbehaving. It seems that when the master ( input )
process hits eof, it exits immediately, orphaning the child ( output )
and user processes.

I believe the correct thing to do is signal the eof to the user
process and wait for the children to exit, but I'm not sure how to
make a pty signal eof.
