When doing this, the parent process will not exit until the child process has exited, in case more messages would be sent. This requires an explicit call to shut down the plugin workers. We set this up as a `process.on('exit')` listener, to shutdown the workers whenever the main Nx process dies. This is "fine", but requires explicit calls to `process.exit` as node won't exit on its own otherwise. ## Expected Behavior To allow plugin workers to clean themselves up on exit, but not require explicit `process.exit` calls, we need to detach them from the main process and call `unref`. This only works when IPC is not being used. As such, we need a different way to communicate with the worker. This PR updates the communication method to mirror the daemon, and communicate over a socket. Additionally, this PR enables isolation during the Nx repo's E2E tests. ## Related Issue(s) <!-- Please link the issue being fixed so it gets closed when this is merged. --> Fixes #
