In backends/bzr.py : mv 'import difflib' to the top of the file to keep from reimporting the library on every function call.

In linux:

Tab 1: (i)python Tab 2: strace -p 'pgrep' Tab 1: import difflib Tab 2: [ note import lookups ] <enter><enter><enter> Tab 1: import difflib

And there's always caching ... maybe something like http://www.djangosnippets.org/snippets/564/

Awesome addition to Django - Thank You!

is fixed in r59. thanks for reporting. I will think about caching function results, sounds like a good idea.
