I need to exit a loop when getlines times out. The documentation says: 
@lines = $obj->getlines([Timeout => $secs,]);

[download]
This method reads and returns the next available lines of data from the object. You can use input_record_separator() to change the notion of what separates a line. The default is "\n".

If a line isn't immediately available, this method blocks waiting for one or more lines, or time-out. You can override the object's timeout for this method using $secs. Also see timeout().

On eof a null array is returned. On time-out or other errors, the error mode action is performed.

A null array is returned for both eof and time-out when errmode is not set to "die". Use eof() and timed_out() to distinguish.

And:

timed_out - time-out indicator

$boolean = $obj->timed_out;

$prev = $obj->timed_out($boolean);

This method indicates if a previous read or write method timed-out.

With no argument this method returns true if a previous method
timed-out.  With an argument it sets the indicator. Normally,
only internal methods set this indicator.

So how do I make use of this? I want to exit the following loop when timed_out is true, so that I can execute another command. 

while (@rlines = $connect->getlines(Timeout =>1)) {
   print @rlines;
}

Timed_out is a boolean value right? According to the info above, I figured I should just be able to say:

while (@rlines = $connect->getlines(Timeout =>1)) {
   if ($pop->timed_out) {
      print "Do something else\n";
      exit;
   }
   print @rlines;

But this isn't working for me. The value of $pop->timed_out is null.
