[racket] (read) interactions

It is possible, but the tricky part is figuring when they are done.
Right now, the box first appears when the program tries to read a
character (perhaps via a call to read-line, perhaps via a call to read
or read-syntax). It does seem possible to hide the box when a) there
is no data that the program hasn't read, still in the box and b) the
program has not tried to read any new data, but I worry about the case
where the box flickers as the user enters a line of data and then the
program processes that line a little bit before reading the next line.

Any ideas?
