SYNOPSIS

See Mail::Box::Locker

DESCRIPTION

Like the ::DotLock locker, but then in an NFS-safe fashion. Over NFS, the creation of a file is not atomic. The ::DotLock locker depends on an atomic open() hence in not usable. The ::NFS locker is more complicated (so slower), but will work for NFS -and for local disks too.
