From the M2 review. HttpEmulator::handle reads with no timeout, so a client that connects and never sends the header terminator parks a task+FD indefinitely; per-conn tasks are also unbounded in count. Wrap each emulator handle in tokio::time::timeout and add a bounded semaphore in serve to prevent task/FD exhaustion. (Tarpit delays remain intentional.)
