There is only one standard input for a process, and the read builtin
reads from it (ignore the -u option for now, since you're not using it).
The `read' in GetReply reads from the same standard input stream as the
`read' in the while loop. Since you've redirected standard input from
/tmp/$USER/tempfile1, GetReply will read from it.
