[Seaside-dev] Seaside 2.8 on Dolphin (work in progress)

[Dale Henrichs]

Esteban,

I've run the example code from the CLS thread and in Gemstone and we 
don't execute the ensure block twice...

We've had 'process copying' in the product for quite a while. For 
Continuations, we had to add a little more copying to the 'process copy' 
logic to avoid having two processes share the same process state.

Hope this helps,

Dale
