Comment 1 for bug 355887

It's not much more than a hunch, but I think that this is something funny going on with PersonSet.getByEmail, which getUser calls -- uselessly, as we never pass an email address in any more. So not calling that may help -- but it would be nice to be sure.

In other news, the login process makes far to many calls to the authserver, and we can probably cut it down significantly...
