It lets plugin code launch a subprocess and stream its output back, running through the same sandboxed bridge that mediates what plugins are allowed to do on the host machine.\n\n**Why**\n\nThis gives plugin authors a supported way to run external programs and receive their output as it streams in, rather than only making one-shot request\/response calls.\n\n- Area: Plugins\n- Names: `process.spawn`\n- Tier: Use it now\n- Useful: 5\/5\n- Signal: 3\/5"}
