if Johnathan's tips aren't helping, you *might* be able to use tags to
delimit vectors and then pass them as streams of scalars. You then have
to keep up with vector boundaries internally in your block.

Depending on what your application is, this could be a solution or can
make things even more inefficient. But it's worth a try!
