If I have a simple setTimeout() function, and set it for 10 seconds...
The the entire server is dead inside those 10 seconds??? Is this true? That's what I heard.
The answer is no. What your link Node.js: How would you recreate the 'setTimeout' function without it blocking the event loop? showed was not a setTimeout blocking the event loop it was a while loop that deliberately blocks the event loop. If you want your server to be fast you do not want to block the event loop. An asynchronous callback such as setTimeout will work great.
Are you trying to block for some reason (like testing or something?)
