// Only processInput:data: is allowed to cause state changes in Vim; all other
// messages should only read the Vim state.  (Note that setDialogReturn: is an
// exception to this rule; there really is no other way to deal with dialogs
// since they work with callbacks, so we cannot wait for them to return.)
//
// Be careful with messages with return type other than 'oneway void' -- there
// is a reply timeout set in MMAppController, if a message fails to get a
// response within the given timeout an exception will be thrown.  Use
// @try/@catch/@finally to deal with timeouts.
