update_tag does not work with Oracle

[GoogleCodeExporter]

When using Tagging-trunk, Django-trunk and cx_Oracle-4.4.1, I can add tags
when a model is created, but I can't update/delete tags. The tags
originally added with the model instance remain, but can't be
updated/deleted :(

Could you please post some example code that reproduces the problem in your 
environment?

I've just re-factored the entire unit test suite in tagging/tests/tests.py to 
be in
individual test cases instead of one amorphous doctest blob.  The only failure 
that I
get with Oracle is when someone tries to limit the number of results contained, 
in
this line

>>> TaggedItem.objects.get_related(l1, Link, num=1)
[<Link: link 2>]

Hi. I no long have access to any of the source code for that project, as I've
switched companies, but it was something with the caching if I remember 
correctly.

Looks like it's working nowadays:

This is with Django 1.0.2, cx_Oracle 5.0.2 and revision 156 of the trunk of
django-tagging.
