I'm not sure about the internals of these file sources and sinks, but
playing around with custom blocks I've found that the function
'message_from_string' does not work properly if the size is set to one
byte (e.g. type = byte, vec_size = 1, when size = type*vec_size). No
throughput is generated by this, as far as my experience goes.
