On the other hand, I've had fairly trivial changes wait for a week to be 
merged because it failed multiple separate testcases that were totally 
unrelated to the change I was making.

If I'm making a change that is entirely contained within nova, it seems 
really unfortunate that a buggy commit in neutron or cinder can block my 
commit from being merged.
