Hi Ben,

First off, thank you for looking into this, it is important, but it is also delicate and few people dare look at this stuff.

This is why it would be good to give it plenty of time to settle in before Pharo 4 release.

I did the scenario you described in #40450 on Mac OS X and everything went as you described: although there were tons of notification messages, the UI remained usable though slow. I did some Zn tests afterwards, including save/restart of the image and did not see any problems.

Thanks for testing.
cheers -ben

What about this notifications
'WorldState>>interCyclePause failed.'

They happen quite often in some situations, for example open Nautilus and search for a class name in the class search dialog.
This inform always pops up if the wait time is small:
[(Delay forMilliseconds: 5) waitOtherwise:[1 inform:'otherwise']] fork
