Description

This has come up a couple of times on django-users: the raising of VariableDoesNotExist in resolve_variable can potentially cause a big performance hit since it may result in the entire template context being stuffed into a string. See:

​http://groups.google.com/group/django-users/browse_thread/thread/60332a3ab2a14fb2/ed01f52525c9af02#ed01f52525c9af02

and

​http://groups.google.com/group/django-users/browse_thread/thread/82df8bb71571fdbf/35089038df9c1976

I'll attach a patch with (what I think is) Russ Magee's suggested fix of simply including the type of object being searched instead of a full repr of it.
