Hi Sean, Ephemerons are working well in Pharo 9, as far as I am concerned, at least from the VM side. We have thoroughly tested them and stressed the implementation with several thousand ephemerons. And we have used them to prototype a precise memory profiler with a student during the summer (yet to be published).
But, there is still missing a good Ephemeron library from the image side. We were planning on having that for Pharo 10, but if somebody wants to take the lead on that, you’re welcome.
