I can, particularly now that the tester builds everything in a docker 
container -- it really didn't like having Ada tests (for example) 
appearing and disappearing based on whether or not the host had an Ada 
compiler installed.  I've also brought the computing resources in-house 
(literally, in my house), so I'm not worried about running out of Amazon 
credits anymore.
