BUG: hash random. in 3.3 exposed reliance on dict traversal order. #2331
fixes all failing tests mentioned in #2331, perhaps others lurking.

still failing.
 Seems to be passing now. Still the python3 numpy issue though
 The fix in groupby.aggregate is incorrect. The test passes, but the problem is still there.
I'm trying out a fix with OrderedDict, (2.7+, will need a shim)

Thanks for the badge btw. :)
 Should be good now. There are still two failing tests  on 3.3, that don't look like
a result of hash randomization, so #2331 is still not resolved.

```
FAIL: test_quoting (pandas.io.tests.test_parsers.TestPythonParser)
FAIL: test_cant_compare_tz_naive_w_aware (pandas.tseries.tests.test_timeseries.TestTimestamp
```
 Thanks. I'll take the PR and address the failing tests separately
