Snapshotting

[matiasinsaurralde]

Hi, would you be able to explain the snapshotting flow?

From what I've seen it should be used as follows:

• A new VM is initialized, with a given WASM module.
• You take a snapshot with snapshot := vm.ReadSnapshot().
• You start another VM and use newVm.WriteSnapshot(snapshot)
• The new VM should contain the same state, e.g. be able to find functions with GetFunctionExport, etc.

Main question is, how do I start a new VM without specifying a raw WASM module (seems that exec.NewVirtualMachine always expects this)

Best.
