Date Tue, 04 Oct 2016 04:30:11 GMT
I tried to force travis to use a standard trusty vm in, so that the VM is assigned 
7.5GB of memory. Unfortunately, travis is still quite flaky, with tests 
only passing some of the time.

Would it be useful to move to another CI? I tried setting up my fork to 
use wercker: 
which failed here:
