lockfile operations are rather OS-dependent. You can't just assume they exist
under Windows. There are reasons many of us hate the non-POSIX compliance of
Windows with a reason---this is one of them.
But you may be in luck as Gabor recently released a package with a _portable_
lockfile implementation, maybe give it a try:
