I went back and looked at the messages, and yes, plain dot-locking is
probably the thing to do.
The problems are
1. If two programs start using two different forms of locks on the same
file, they'd better do it in the same order. It's better to just lock
once and not gild the lily.
2. Rumor is that some NFS implementation will lock a file with lockf
but can not subsequently unlock it.
