I've attached a patch that does the following:
* Added a `handle_response` method to `BaseHandler` to factor out duplicated
code in `ModPythonHandler`, `WSGIHandler`, and `ClientHandler`.
* Replaced `resolver` temporary variable with a `resolver` method to ease
refactoring of `get_response` met

Slicing is cool, but I'm +1 for deprecating it and using .limit().
Slicing in my mind should return an iterable and you shouldn't be
messing w/ properties on that iterable, even though somethings you
might want to.
For example:

Ok, thanks for your reply, I'll try to submit a patch with an original
exception stored as soon as I figure out how to do that.

Unfortunately, no. I understand transaction isolation levels. By the
way, I'm using MySQL InnoDB which has similar isolation level settings
to PostgreSQL. Regardless of the isolation level, the one of the two

One other question (for now). I just did a ticket search for
FileField, and I found a few tickets (#5655, #5619 in particular) that
seem to be legitimate beefs, but their patches rely on pre-#5361 code.
Should I consider #5361 to be on par with Malcolm's (many) refactors

Incidentally, qs.fetch() need not be equivalent to list(qs). It could just

I've seen ticket #4339 ( http://code.djangoproject.com/ticket/4339 )

The ticket is in design decision needed. It's a little change, that

another thing i jsut ran into:
this causes an IndexError
Model.objects.filter(something)[0]
you have to add the colon before the 0
Model.objects.filter(something)[:0]
the limit(0) would not bring this error, it would not let

I think this hits the point.
What do you think about this: a QuerySet fetches a chunk of elements, say
100, as soon as you request at least one? So aQuerySet[0]
