Thanks for this, I have noticed this niggling problem for a while here
and wasn't sure how to solve it.

This is ok in most cases, but I have some very large queries, sometimes
with the uniqueness towards the end of the query (and was getting the
same problem again). So I changed the above line to:

$obj->{mv_cache_key} = generate_key($opt->{query});

I understand why the values are truncated but when you have queries with
large numbers of sub-selects the above might be better. I certainly
haven't had any problems with it since the change.
