Yes, that's much more elegant. I didn't realise that call/answer could
be used at the session level. (To keep your implementation parallel to
my algorithm which reproproses a login window on failure, that would
presumably be:

   ^ user ifNil: [
	[user isNil] whileTrue: [user := root call: SeasideLogin new]]

That requires a 'cancel' option to be fully usable, which I haven't
had time to put in yet. Should be trivial though.)
