Target: main

Description of Change

  • utilityProcess.postMessage() no longer crashes the main process when called after the child has gone away (e.g. from the 'exit' listener, or during app shutdown while a utility process is still running); it is now a no-op in that state.
  • Adds a crash-case fixture covering both paths.
