 I'll like to take the chance of thanking the people behind `mio`, `tokio`, 
 `async_std`, `Futures`, `libc`, `crossbeam` and many other libraries which so
-much is built upon. Reading and exploring some of this code is nothing less than
-impressive. Even the RFCs that much of the design is built upon is written in a
-way that mortal people can understand, and that requires a lot of work. So thanks!
