test_chdir is a Jython-specific test. It reveals a bug in the tempfile module that CPython noticed (http://bugs.python.org/issue14255 refers) but only fixed in Python 3. I'll copy this for Jython. It suppresses three of the chdir failures.

I'll look into the other failures as distinct change sets. Jython's tempfile has fallen a little behind CPython's. I'll take in that and the problematic use of os.name too, but they're not the source of these failures AFAIK.
