This topic came up a while ago, see this thread:
http://thread.gmane.org/gmane.comp.security.openwall.john.user/202/
I don't know why gmane doesn't regognise the tread when pointing

http://thread.gmane.org/gmane.comp.security.openwall.john.user/201/

I also don't know if there are any newer developments.
