That's incorrect.

At the time I formulated this patch, asyncore/asynchat were slated for
removal from the standard lib unless somebody stepped up and made it
work correctly after the str/bytes transition. That's what
asyn_py3k.diff and its predecessors do, as well as adding sorely-needed
docstrings to the module. This patch may be a little more complete than
the currently committed code, or it may be largely redundant. The
docstrings, at least, are still needed.

The asyn_py3k_restructured.diff patch is a superset of asyn_py3k.diff,
which additionally removes the "producer" type from the module,
replacing it with iterators. This is controversial, and seems unlikely
to be committed.
