There was also a UserDict thing to sort out for Python 3 which
isn't taken care of by 2to3, see http://bugs.python.org/issue2876
However, the biggest annoyance of the index_db stuff was my
unit tests on Windows - it turns out repeatedly creating, using,
closing and deleting a file with the same name was a bad idea.
Something was keeping a stale handle to the file as it wasn't
always getting deleted. In the end I just gave in and used a
different temp file for each tests, and it works fine. Weird,
also rather frustrating - but the tests pass now :)
I wonder how SQLite3 support in Jython is coming along...
