I used the wrong word. What I mean is what I call "remote control" world 
cycles. In Cuis, #doOneCycle is only called from PasteUpMorph>>mainLoop. 
The World itself is in control.

In Squeak, (indirect) senders of #doOneCycleNowFor: include 
DialogWindow, TileMorph, MenuMorph, AllPlayersTool, CategoryViewer, 
EventRecordingSpace, and several tests. None of those should control the 
World.

Still, the problem we have in Cuis is that a ModalMenu stops the world 
while active. Maybe the solution is not to use modal menus and dialogs 
at all.

Of course! Still, I wasn't sure if you hadn't gone the not-so-nice way 
of implementing your own ModalMenu and cycling the World yourself. Good 
that you didn't need to do that!
