Hi,
I seem to have totally lived in the dark about the existence of the VM module. 
I have two questions that I hope a kind knowledgeable soul could answer and I could not find the answers in the docs.
 
1) Does the VM module run contexts in separate threads? If not, could it in the future?
2) If answer was yes to the previous question, or will be in the future - could the cluster module be reworked to use separate contexts instead of processes?
 
 
1. No. No.
2. No.
 
If you want just to scatter vm instances over multiple child processes, any good node.js developer can came up with such solution in an hour. There are "sandbox" and a few other modules already doing it (I saw at least one webworkers implementation based on this).
 
As for threads...Why do you want to use threads instead of child processes? I don't believe it has any performance benefit, and sharing states between different v8 instances is impossible anyway (read as "nobody would do that").
