Thanks for this; it solves my problem >between< processes.
But it does not work >within< a process; it is possible to
take the same lock twice in the same process. However, as
previously mentioned, I can deal with that by accessing
the file via a singleton.
Now I have noticed that closing the file releases the
lock, so I wonder if use of F_ULOCK is really necessary.
I am calling it in case it releases resources that the
close() might miss.
