test failure: test_copyable.Copyable.testFailure1

I get this locally (under tox, on OS-X), and I think dawuud is getting it too.

Neither the buildbot nor travis is showing this one.

Oh, so, I moved foolscap/ to src/foolscap/, but the old .pyc files were still sitting around in my source tree. Trial (and tox) tried to run those instead of the ones that were installed into the virtualenv. When I got rid of the old foolscap/ directory, this failure (and #251) went away.

The test in question wanted to produce a traceback, and I think the lack of a source file (test_copyable.pyc was present, but no test_copyable.py) meant it couldn't.

Closing this one. For anyone else who has upgraded a git checkout of the foolscap source code, please rm -rf foolscap before re-running tests.
