You know Concurrent Smalltalk was certainly like that too. Now my point is that this is good to share ideas that there are old or not. Already discussed or not.
Yes, that's why i asked , because i didn't understood your message.
So I repeat it. Right now on my desktop when I open any Smalltalk I still have some old ideas moving inside. And we would like to create a different world in which even old ideas that were discussed long time ago but never arrived to my current desktop could be discussed. If we want people to invent the future, they should at least know the past and gets also ideas from others.
For example I would like to see the cost of it at the level of the GC.
The main problem here, as also mentioned in discussion, is how GC should deal with far references, i.e. how to determine correctly when object which is referenced by some far ref become garbage.
May be a lifecycle like in Corba solution is needed at the level of each vat.
As for the rest of it, its not any different from usual approach: GC could sweep a single vat space at any moment it wants, regardless of what other vats currently doing.
