Hi,

My 2 pence... I think the Driver Toolkit might be able to deliver a painless addition of features to the language, by easily interfacing with existing libraries. Not everything should be built into the runtime.

An image that popped up in my mind was that we could send a "freeze" command to a process and then be able to retrieve the process heap. It could then be moved to another VM, and the process could be thawed... it wouldn't notice a thing :-) Maybe some of this can be included in the gen_ behaviours, but for the heap retrieval/restoration the runtime will have to cooperate.

Vlad
