A modern Linux system can scale to a large number of processes just fine. (With a bit more configuration, it can even merge identical memory across processes, with ksm.) And if you find yourself running tens of thousands of connections that are all active, you can always move to something more scalable. In practice, something else may end up being your bottleneck. Meanwhile, this seems easy to get up and running with.
