Type the following after M-x eshell RET:

echo "1+1" | bc

and then the return key. Instead of the expected answer 2, eshell
displays:

bc 1.06
Copyright 1991-1994, 1997, 1998, 2000 Free Software Foundation, Inc.

For details type `warranty'.

now type the return key again. Here the answer is shown:

2

type the return key again. Nothing happens. Eshell blocks. Control-C
shows:

(interrupt) use quit to exit.
