From the keyboard of rbj@uunet.UU.NET (Root Boy Jim):
:File locking is easy, unless, of course you are using NFS.

Use lockf (fcntl) instead of flock then.  And risk hanging forever
should the lockdaemon go south.  Actually,  I haven't had too much
trouble with it in the last few months on this particular machine,
but on other convexen here there have been occasional anomalies.
