Thanks.

I haven't tried myself, but from analogy with other subunit tools:
  ./bin/test --subunit | subunit2junitxml

The formatter doesn't control exit codes, so I didn't really think
about them in this patch. Should I produce a follow up?

Oops :) I've changed it to say 0.9.2, and subunit to say 0.0.5, which
is the actual version I've tested with.

Sidnei explained it correctly. This particular file is only tested if
you're running a Python with --with-pydebug set, so it's easy to miss
when you make a change.
