- Tests are based on oslotest.base.BaseTestCase, which uses the
NestedTempFile fixture, which uses the TempDir fixture, which adds a
cleanup routine to remove the base temporary directory it creates.
There's therefore no need for tests to clean up this directory, so all
the code that does that is removed.
- The eventlet incarnation of tests was trying to make use of the `env`
external without whitelisting it, resulting in an ugly red deprecation
warning. This commit adds `env` to whitelist_externals in [testenv].
- A handful of typos in the Beowulf quote are corrected.
