Q: How come when I automate the passwd program to change passwords 
for me passwd dies before changing the password sometimes/every 
time?

A:	What's happening is you are closing the handle before 
passwd exits. When you close the handle to a process it is sent a 
signal (SIGPIPE?) telling it that STDOUT has gone away. The default 
behavior for processes is to die in this circumstance. Two ways 
you can make this not happen are:

	$process->soft_close();

	Which is new in 1.04.  This will wait 15 seconds for a 
process to finish up before killing it. 
	
	$process->expect(undef); 

	This will wait forever for the process to match an empty 
set of patterns. It will return when the process hits an EOF.
