ERROR: test_connections (__main__.TestProcess)

    os.remove(fname)
WindowsError: [Error 32] The process cannot access the file because it is being used by another process: '$testfile'

Only saw this on appveyor, probably because it's slower than my virtualized Win 7 box, hence this looks like a timing / sync issue.
