Ah, that jibes with what I *thought* I knew much better (though still a
difference, since you imply that changing multiple, unrelated elements
can be done without a lock).  So I'm not completely off-base, but the
particular example I showed doesn't require a lock since it's only
changing one element of the structure.  Is that correct then?
