Odd. The last time I looked into this, it acted as if it was locking over NFS. I ran one little Perl program on the Alpha, and a second on an AIX NFS client machine. It certainly acted as if they were respecting each other's flock(). And, yes, I checked the Perl sources. It's definitely using flock().
