There's a race condition here in which there's a small
chance of more than one person succeeding in editing
the file(s) and hence the reason for the advisory
locks patch (read on).

"cvs edit -c" is exactly what you describe above.  The
caveat is that anyone could do a plain "cvs edit" or
"cvs edit -f" to bypass or override the check (unless
one patched the patch).
