Two reasons:
1. there does not appear to be any equivalent functionality in Django.
2. the code to integrate Storm with Zope's transaction manager had
already been written.

Olaf's decision to reuse the Zope's transaction module for Pylons
integration reinforced my own decision.  Besides, we are talking about
a small fraction of the total Zope 3 infrastructure.  We aren't
pulling in the component framework, ZODB or any other large pieces.

Lastly, reusing the code means that we benefit from storm.zope
improvements (e.g. to implement two phase commit you need a global
transaction manager to plug into).

I'll keep publishing to my branch, and ask for help when I need it.  Thanks.
