I honestly can't remember why I initially put that there -- possibly
because I had a notion that some modifications to the structure might
not need to be so closely synchronized with other processes as to
need have modifications covered by a LW lock, but not wanting them to
linger forever. It may be completely bogus.
The problem is that I don't have a very clear sense of what it really
does, which is not helped much by having done a few years of Java
programming, where the same keyword seems to have a vaguely-similar-
but-not-really-the-same meaning.
