Failed look-up will not remove the row from the pipeline

[thbar]

If a foreign key lookup fails, the row will still be processed by the before_write processors apparently.

A small repro is needed before someone can work on this.

Work-around: the user can check for nil values in the row later in the pipeline (not sure transforms will be run, but before_write surely will).

It only happens as part of a transform. An error in a before_write, for instance, will stop the processing.
