If Pharo's gc algorithm is concurrent => maybe yes, otherwise surely no : if I'm not wrong gc starts inside VM when checking allocation spaces during a basicNew or alike. And the VM seems stuck, at that moment.
One can try to create an ephemeron and check it every 100-500 ms, refreshing it if it's still here (so it will stay in new space). But it shift the question to the definitive target group : the VM guys !!! Chers from Lombardy, Davide (PS : but creating the ephemeron could start an invisible gc !!!)

Hi I would to be able to see when an incremental GC is happening. is there a way to know when a GC is happening?
