I tried the tests after running into a crash in a real application, which I can reproduce with Tornado easily:

import tornado.ioloop
import tornado.httpclient

http_client = tornado.httpclient.AsyncHTTPClient()
def done(r):
print "done!", r
response = http_client.fetch("http://google.com", done)

tornado.ioloop.IOLoop.instance().start()

    I built libcurl 7.21.2 for x86_84 on VC9 and rebuilt pycurl-7.19.0 to use it, and I still get the crash.
