This screws lots of things up and is just plain unnecessary, everything will
get cleaned up properly on it's own. Most notably this was causing root
eb's to be evicted forcefully which meant that any readers still doing
anything would block trying to grab the root eb since it had a ref count of
0. Thanks,
