So in Joe's recent metadata commit he added a test
for regather, while this test works it does run the
entire benchmark twice, which isn't exactly ideal.
*stares at 22h old Newton build* this commit instead
stops gathering metadata as a seperate role and simply
runs Browbeat without gathering metadata, doing the same
test without taking twice the time.
