in thread getfile( $filename )

Well, File::Slurp purpose is to read the entire file, so that module itself is wrong for large files. The best I've come up with in that case is something along the lines of 
my $FH = IO::File->new ...

until ( $FH->eof ) {
  my $chunk = $FH->read( ... )
  # process $chunk
}

which doesn't really lend itself to modularization because the processing is always different.

    Then pass in a function reference -- something like this: 
    sub chunk_at_a_time
{
  my $FH = IO::File->new ...

  my $func_ref = shift;
  my @func_args = @_;
  until ( $FH->eof ) 
  {
    &{$func_ref}(@func_args);
  }
}
...

My_Module::chunk_at_a_time( @file_args, \&some_sub_name, @sub_args);

    (I dashed this off quick -- the syntax may be wrong, but you get the idea.)
