On every other toolkit (and at least GNUstep, which I just verified),
the menu bar doesn't interfere with the usual event loop.  Though
unfortunately GNUstep doesn't implement willHighlightItem, so I can only
implement help text for macOS.

The only time a nested event loop is run is when a menu is created with
`x-popup-menu', and that's to make it easy to return a value from that
function.  That's also what I was referring to by "regular menus".

Thanks.
