I haven't followed this thread, but can answer that question literally
<wink>:  it's code synthesized for the seventh doctest example in
Lib/_threading_local.py's module docstring.  The file name is
constructed by this line in doctest.py:

            # Use a special filename for compile(), so we can retrieve
            # the source code during interactive debugging (see
            # __patched_linecache_getlines).
            filename = '<doctest %s[%d]>' % (test.name, examplenum)
