read_csv should accept unicode objects as urls
Hi,

I have tried the following with
pandas-f014b01af7bd2d03266697e672c2d41daded3fca.zip
and
pandas-0.10.0.tar.gz

The unit tests on my Pandas build are failing with:
# 
## FAIL: test_read_csv (pandas.io.tests.test_parsers.TestCParserHighMemory)

Traceback (most recent call last):

Ran 2934 tests in 193.600s

FAILED (SKIP=44, failures=3)

I have compiled python, cython, numpy, etc. myself. Are there any dependencies or compile options that I am likely to be missing?

Please let me know if there is any other information I can provide to help identify the problem.

Thank you
