Description

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.
