The Ubuntu test runner now configures and compiles CPython out of tree.
The source directory is a read-only bind mount to ensure that the build
cannot create or modify any files in the source tree.
For testing the source directory is re-mounted writable. 15 test modules
depend on writable sources and lack of .pyc files slows CI down.
