Keep in mind it only breaks if you try to pickle it. I imagine most people
don't pickle evaluated querysets.
If we really need a hack to solve it then it would be easier to detect
`datetime.datetime.now` in the `Field` constructor and replace it with a
reference to, say, `django.db.utils.current_time` that is a regular
module-level function. At the same time raise a deprecation warning.
