NetworkInterfaceTest tests are required to block using the fixtures interruptible() implementation to ensure the versions that run with the baton can make forward progress. There are some cases where the main thread blocks without doing so, which can hang the tests and cause difficult to diagnose failures. We update these locations to properly run the baton while blocking.
