Fix bug 934575. As Chris pointed out in the bug, there is a downside to this approach to fixing the bug, in that a manager will no longer be able to use context.reply(). However, it wasn't being used at all, and it's no loss in functionality. A remote method can still return multiple values (in response to a multicall()) by using yield.
