GbxDelegate>> fetch* will error if traversal size exceeded
The behavior for GbxDelegate >> fetch* (such as GbxDelegate >> fetch:varyingOOPsAt:) was rearchitected in release 7.0 to use thetraversal buffer mechanism. However, when the object size exceeds
the traversal buffer size, the fetching mechanism does not work and
will result in a walkback, Message not understood: #fetchMoreTraversal.
Workaround:
Ensure that the traversal buffer size is large.
