I don't see how the delays can be new as the menus would have to be
recalculated under the old code anyway...

It is quite noticeable, though...

I notice this in the Apple docs[1]:

    If populating the menu will take a long time, implement
    numberOfItemsInMenu: and menu:updateItem:atIndex:shouldCancel:
    instead.

I wonder if that's possible for us. ns_update_menubar is a big,
complicated function that I've not been over in depth to work out what
it's doing, so I don't know if it would be practical to break it up
like I suspect using those two methods would require.

Sorry, I was unclear. This is an older problem. I'm not sure when it
was introduced.
