+* Infinite loop in Persona sign-in flow. When the backend API /users/login fail
+  to connect to the Mozilla Persona APIs (connection timed out etc.) - the
+  /users/login returns a 500, and then the Persona Javascript SDK calls the
+  logout API /users/logout and then it calls the login API again; as a result
+  the entire sign-in flow falls in a infinite loop.
+
+* Automatic log out from Persona. Persona forces a user to login, again, when he
+  opens SWeeT store while being logged into Persona, through a different
+  site. Persona requires the user, every time, to explicilty say that he is
+  agreeing to share the email adress with a site that is using Persona API.
