	Here's a bad answer:

	# Returns hashref w/ each file being a key that has a value of 1.
	sub get_open_files {
        	my($filenames) = {}; 
		my(@lsof_open_files) = `lsof -p $$`;
		shift @lsof_open_files;
		for(@lsof_open_files) {
			$filenames->{(split(/\s+/, $_))[8]} = 1;
		return $filenames;

	my($before_open_files) = get_open_files();
	$fh = IO::File->new_tmpfile    or die;
	my($after_open_files) = get_open_files();
	for(keys(%$after_open_files)) {
		if(! exists($before_open_files->{$_})) {
			$tmp_file_name = $_;
	print "File opened is: $tmp_file_name\n";

	No, I haven't actually tried to run this. But is seems like it would
work in theory.

	I'm sure there's some magical way of doing this but I wouldn't know
