This didn't work for me on django1.1,

The following did though:

def invalidate_template_cache(fragment_name, *variables):
  args = md5_constructor(u':'.join([urlquote(var) for var in variables]))
  cache_key = 'template.cache.%s.%s' % (fragment_name, args.hexdigest())
  cache.delete(cache_key)

Wraps the invalidation function in a template tag.
