If I understand correctly, your suggestion for avoiding deadlock relies on the fact that a given thread can really only have one object locked at a time, i.e. after you LOCK an object you can only assume you own it until you LOCK another object or return to some quiescent state. Is this right?

If so, the question is whether it's sufficient to be able to lock just one object at a time. Maybe it is, but some more formal consideration of that might be a good idea.
