I brought this up in the forums yesterday, due to my session cache
filling up as the result of large queries. Gavin also suggested
Session.clear().

evict would work fine for me, but it would end up something like this:

for (Iterator it = query.iterate(); it.hasNext();) {
  Cat cat = (Cat)it.next();
  session.evict(cat);
  // do some calculation on cat
}

Maybe it's silly to pull it into the cache via next(), just to evict as
the very next step.

So, how about 
  query.setTransient(true)?

All objects returned by the query would be transient and not take up
space in the cache.
