MiniObject.take

Modifies a pointer to point to a new mini-object. The modification is done atomically. This version is similar to MiniObject.replace except that it does not increase the refcount of newdata and thus takes ownership of newdata.

Either newdata and the value pointed to by olddata may be NULL.
