Well, you did indeed fix it with:

Have you tried strace'ing/truss'ing tsql when it reads an input file?
Using readline(3), it issues a read(2) per character, not counting the large
number of failed ioctl(2)'s in the beginning. We have the code in tsql to
do the readline, why not just use it when we are not connected to the tty?
This way, in the future, when readline(3) decides to do something else bogus
with the input stream we are not going to be affected.
