Delancey fix

I believe I have worked out the segfault issues with Delancey, the service that augments del.icio.us to keep track of which bookmarks you click on the most. If you use Delancey and are still have random issues with it then please ping me.

On a related note, I spent a good part of the weekend starting to port Delancey over to Python using the Django framework. (Delancey is currently written in Perl on a custom framework I developed.) My first impressions of Django are very positive. I admire Django's design philosophies and the framework seems to do just enough of what it should do, and does it well. I look forward to learning more about both Python and Django, and porting Delancey feels like a good place to start.
