The biggest one, in my book --

 - If you export a reference to a LWO to another object, which keeps
   the reference after the completion of the current thread, the LWO
   will be -duplicated- precisely as arrays are.

Since we've gotten used to being able to store object references in
all kinds of ways -- e.g. use them to index mappings -- this is a big
change. If you get it wrong, you'll have duplicate LWO's all over the
place that don't end up garbage collected.
