These tests are going to fail on the automatic testing system; it is much slower than our local machines.  Can we do something like:

```
def _skip_if_travis():
  from nose.plugins.skip import SkipTest
  if os.environ.get('TRAVIS', None):
    raise unittest.SkipTest()
```

Then on the first line of each test:

```
_skip_if_travis()
```
