I've also changed the return type of operator ->. There's no need to create a copy of the shared_ptr.
I'll use these changes in my implementation.
Actually, it seems that I will not be able to have the lock as member of LockProxy since it's boost::noncopyable. LockPointer's operator->() returns a LockProxy by value and needs to copy all member of it to do so. I can't see any way around this so I need to have a pointer to the lock in LockProxy. Perhaps someone else can see a way to not have to use a pointer to the lock? :.:: mattias
