Version controls diffs of large text files kill the system

We have some large text files (they are some data files we deal with) and when you try to view "last revision" or a revision with them it bombs (i.e. the service's cpu usage goes to 100%, and things come to a screeching halt).
Looks like the issue is in: versioncontrol/web_ui/changeset.py
The _content_changes method tries to do a diff of anything that isn't a binary. This is fine for most text files, unless they are big (like even 5 to 10 megs seems a bit much for the diffing method used). Anyway, I simply added the following to _content_changes:
if (len(old_content) > 100000 or len(new_content) > 100000):
(Sorry if it isn't proper pep8)
It looks like you have a max_diff_bytes but that only effects the diff results. Ideally you would want a threshold before you have the diff results.
