> libprocess's {{IOTest.BufferedRead}} writes to the current directory. This is bad for a number of reasons, e.g.,
> * should the test fail data might be leaked to random locations,
> * the test cannot be executed from a write-only directory, or
> * executing the same test in parallel would race on the existence of the created file, and show bogus behavior.
> The test should probably be executed from a temporary directory, e.g., via stout's {{TemporaryDirectoryTest}} fixture.
