Sorry, RAM is too expensive these days to run two instances of Chrome on the same system. Maybe the time has come for some VC-backed startup to start a rent-seeking business for streaming your development environment from the cloud?

I know there were attempts for this before but they were just banking on the fact that the average dev env is an absurd collection of hacked together tools that is both fragile and nigh impossible to set up for new devs. Now they have a financial angle as well /s
