Expat 2.1.0 Beta was recently announced:
which contains (among other things) a fix for a hash-collision denial-of-service attack (CVE-2012-0876)

I'm attaching a patch which minimally backports the hash-collision fix part of expat 2.1.0 to the embedded copy of expat in the CPython source tree, and which adds a call to XML_SetHashSalt() to pyexpat when creating parsers.  It reuses part of the hash secret from Py_HashSecret.
