Flushing a FollowTail wheel.

[Mark Swayne]

Is it possible to flush the contents of a POE::Wheel::FollowTail wheel?
I am using one to monitor a file that is left with a non '\n' terminated 
line at when the process that creates it is finished.

What I'd like to be able to do before closing is somthing like:

sub finish_file {
  my $heap = $_[HEAP];
  $heap->{wheel}->flush;  # this should generate an InputEvent with any 
dangling bits left in the buffer.

  # do other stuff here
}

Or even better:

$heap->{follow_tail} = POE::Wheel::FollowTail->new(
       Filename   => $logfile,
       InputEvent => 'got_line',
       ErrorEvent => 'got_error',
       FlushAtClose => 1,    # Enable an automatic buffer flush as the 
wheel is destroyed.
   );

TIA,
