What is a process group?  I know the following things:

	You can make a process the process group leader via setpgrp();
	   (with some versions of UNIX)
	You can send a signal to all members of a process group

I have inherited some code which does
	pid = setpgrp ();
	ioctl (2, TIOCSPGRP, &pid);
to change the process group on the terminal.  Why would someone want to
do this?
