Python 2.3.4 doesn't accept a 'protocol' keyword arg for cPickle.dumps,
and I sometimes get a string back rather than array.  So I've changed the
code to address these.

The docs say this syntax should use pickle protocol 2, but the value of
the picke does not begin with '\x80' like my manually-created protocol 3
pickles do.  So I'm not sure whether it is or not.  But the test program
is working in 2.3 and 2.4, and my application is working.
