#7847: [Cleanup] Unused imported modules in Django
---------------------------+------------------------------------------------

   Status:  new            |   Milestone:            
Component:  Uncategorized  |     Version:  SVN

---------------------------+------------------------------------------------
 I've removed many import statements of modules that were not used,
 throughout Django (see patch attached). That won't necessarily improve
 performance but it's a good cleanup at least. I ran the full test suite
 several times. I do get some failures/errors but I don't think they're
 linked to the changes in the patch since I get the exact same errors from
 a clean check out. My test environment (based on Windows XP+MySQL) is
 probably not 100% reliable and there might also be some problems caused by
 the latest big changes in trunk. Just for the record, here is a sample of
 the failures/errors I get:
