I think this statement (and the patch) is wrong. You also need to change
the byte string hashing, at least for 2.x. This I consider the biggest
flaw in that approach - other people may have written string-like objects
which continue to compare equal to a string but now hash different.
They're unlikely to have rewritten the hash algorithm by hand -
especially given the caveats wrt. differences between Python integers
and C integers.
See the CHAR_HASH macro in
http://hg.python.org/cpython/file/e78f00dbd7ae/Modules/expat/xmlparse.c
It's not *that* unlikely that more copies of that algorithm exist.

Martin
