Description

When you send rows of data into a transform that doesn't accept it we should throw an error.

This can occur if the reading transform has an option to read from input files or from an input field.  In case the "read from field" option is disabled you get the effect that the input buffer of the transform is just filling up and the transform blocks.  The pipeline then never finishes.
