+# Thoughts
+
+- After converting to std::future::Future which is not much work:
+- Implement server.rs with a simple listen function
+- Can only accept delay requests like the ones we make
+- Implement a simple timer reactor using
+  - A thread
+  - Veddeque to store timers/wakers
+  - thread::park_timeout() / thread unpark to add new/wake up and call wake once a timer has expired
+
+We now have a client and server running our own async runtime single threaded. How many "threads" can we achieve? More than OS threads on a sinlge thread?
+
+Or is this too much work for readers to do?
