Description
env.get_known_users is an extremely expensive query if you have many sessions and attributes. The timeline uses it to populate a user name→email map for RSS author emails. This map is populated even if format != 'rss'.
Simply wrapping the email_map construction with an rss format check gives a large speedup for normal timeline use.
In the future, the user schema should extracted from the session or at least cached in-process.

Fixed in [9937], together with a bug in the report RSS template that prevented the author tags from appearing at all.

In 0.11, the email_map is effectively only done for RSS requests.
But you're right, even so, that's probably an important aspect to optimize when we refactor the user/group handling in 0.12.
