The underlying implementation of Perl's flock() may differ widely based on OS (maybe flock(), lockf(), or fcntl()) but I'd think that Larry and co. would be careful enough to make sure the Perl version works everywhere.  One huge advantage of Perl disappears if you can't abstract away those OS differences.
