PEP 3156 should add a new API for adding a pipe (either the read or
write end). Someone worked on that for a bit, search last week's
python-ideas archives.

The iocp branch now has all these refactorings.

Do you know how to write code like that? It would be illustrative to
take the curl.py and crawl.py examples and adjust them so that if the
protocol is https, the server's authenticity is checked and reported.
I've never dealt with this myself so I would probably do it wrong...
