 situation is even legal.
 It's usually a non-issue; however, MarshalByRefObject and
 ContextBoundObject don't have the Sequential attribute applied, so under
 the MS CLR, anything that derivces from these cannot have a
 StructLayoutAttribute applied.
+------- Additional Comments From vargaz@freemail.hu  2003-08-28 07:19 -------
+If a class is marked sequential, all its parents must be marked
+sequential as well, since a derived class can't change the layout of
+the fields it inherits from its parent. It is documented somewhere in
+the spec, but I couldn't find it.
+So the only problem here is that the runtime doesn't verify this
+condition. In fact, it does almost no validation. Someday, somebody will
+implement a complete verifier for mono. In the meantime, I'm closing
+this as WONTFIX.
