This unit test is currently locking up on Travis, and has been for quite some
time. Let's try skipping it in for now, and then try and figure out how to
inject into all of the system interpreters reliably.

Right now it's currently failing to find python3.3-dbg, so hopefully this'll do
the trick. https://travis-ci.org/lmacken/pyrasite/jobs/20793923

Before this fix, the following exception gets thrown on Python 3.3:

TypeError: Type str doesn't support the buffer API

Thanks to https://gist.github.com/ssokolow/5496286

This will hopefully get 2.5-3.3 working on travis-ci, as nose should be able to
discover everything just fine.

Work around meliae unicode bug

As described here (https://bugs.launchpad.net/meliae/+bug/876810)
simplejson will write out unicode escape sequences, but won't read
them.
