We need a way to identify when a device is running more than one Code Engine instance about thingsjs

Good point! I think we discussed it briefly at the last meeting -- my proposal (in the meanwhile) would be to divide the total system available by n if n code engines are running on the same device (would there be a way for a code engine to detect if other code engines are running on the same device?).

I think this is an OK solution, as logically, in a real deployment, I don't see why we would need to run more than one code engines per device. We do this pretty much only for testing.

Yes I think we definitely need the ability to determine how many CodeEngines are running on a single device, but I don't know if we should assume or impose restriction that there will be only one CodeEngine running per device. Although in practice a single user would have no reason to run multiple CodeEngines, many cloud/servers are time-shared and there could be multiple users ssh'ing into the same machine and running a CodeEngine per logged-in user. In such cases there will be multiple CodeEngines running on the same machine and the user would not have control over other users taking up resources. So I think we should allow multiple CodeEngines on the same device as long as we can detect how many CodeEngines are sharing resources.
