  Log:
    .travis.yml: avoid using -j3 for osx
    
    osx build has failed too often. we don't know why.
    
    To know which test hangs forever, we might want to have hard timeout for
    all test case (like 9min, slightly less than no-output timeout) in test-all.
    But it's a little hard to implement and I would workaround an unknown
    cause somehow.
    
    It's known that -j is harmful for some tests in test-all. Let's try to
    remove it first, and if it doesn't work, I'll resurrect -v option to
    easily know which test is the culprit.
    
    Slow correctness is much better than fast false-positive.
