I can't think of any either, but then I use MacOS more than Linux or 
Windows.
Does that mean that it would be OK for a toolkit to support just one 
menubar per application on non-MacOS platforms?
All allegedly cross-platform toolkits I know treat a menubar as a 
property of a window or even as an ordinary widget that you can place 
inside a window, which causes several problems for the Mac OS 
implementations of those toolkits.
A related problem with Mac OS is that when you close the last window of 
an application, the application doesn't terminate, it's menu bar is 
still there. You can still open a new document from the menu. When you 
click on the icon of an open application that doesn't have any windows, 
a new empty document window should be created. I know of no 
cross-platform toolkit that supports this behaviour.
