The application xfdiff (part of XFCE desktop at http://www.xfce.org) uses 
forks and pipes stdout, stderr and stderr between xfdiff, gnu-diff and 
gnu-patch and achieves a graphical version for diff and patch. At a point 
there is a triangular configuration between 3 independent processes. Also as 
a part of xfce you will find xfglob (much simpler than xfdiff), which is a 
utility to find files on your hard drive, and which pipes stdout and stdin 
between xfglob, gnu-grep and glob (a command line utility that comes with 
xfglob).

In using pipes for file handles 0,1, and 2, these programs at times use 
sleep() for one second to ensure that the process reading the pipe manages to 
finish before the process writing to the pipe exits.
