I don't understand what the hammie.py patch has to do with this. I've
checked everything else
in.

There is a safe method for storing pickles, but it isn't used
consistently, and there's code duplication. The enclosed patch contains
fixes for the tte script and a few other things I've reported... the
dnscache changes are even related... but you *really* should apply the
whole thing ;-).
File Added: safe_pickle.patch
