Ah yes, thanks. I didn't not check that property...I think a FAQ item
would be useful here. Complex issues like this, binary serialization,
etc probably should be documented somewhere. An editable wiki would help
(is there one? :) I'm finding issues as I port our complex .net app to
mono and it would be nice to put them somewhere web accessible.
