Is that true? I don't know the suite well but a casual peek at  
Test::Builder's guts looks like it goes to STDERR and STDOUT  
alternately depending on whether the output was from failure or from  
intentional calls. I think the reason it never interferes with test  
harness is that the output is escaped/#commented.
