I would agree with that assessment, as long as it were followed by the
disclaimer, "but then, 'almost solved' means 'not solved.'"

If I had a Sun machine, I'd avoid NFS-mounted mailboxes like the
plague.  (I'd shun cliches, too; but that's another story.)

Well, I apologize if I ruffled any feathers.  What really sets me off
is when a vendor creates a problem for which no reasonable workaround
exists, and then lets it endure for a long time.  Sun's motto should
be: "Our Lockd Matches Our NFS Protocol: They're Both Broken".
