In general APSW does not look ready for the Python 3.3 Unicode
implementation. Example: src/statementcache.c:217

    Py_UNICODE *out;
    PyObject *res=PyUnicode_FromUnicode(NULL, size);


Python 3.3 docs:

"If the buffer is NULL, PyUnicode_READY() must be called once the string content has been filled before using any of the access macros such as PyUnicode_KIND()."


The abort() in the traceback occurs precisely because PyUnicode_READY()
hasn't been called, so I'm closing this as invalid.
