I re-wrote the SSL module for CPython back in 2007, and as part of that delved into the socket and httplib modules, further than I wanted to go. The httplib module relies on the socket module's not actually closing the socket when it gets GC'd. It passes the file descriptor off to a callback function, and drops the socket object, assuming that the file descriptor will stay open so the callback function can read from it, until someone (presumably the callback function) closes it. (This apparently was originally done to work around the absence of dup() on Windows.) I believe it was re-engineered in py3, but am not sure what the status is in py2. I could easily see this leading to something similar to what you're seeing.
