Aah I see the loop now. But now you are polling and using CPU. And you still 
have the problem of you are only using one socket here in this example and 
you have implemented a trivial task. 

Implementing a basic read versus implementing a real server is very different 
in complexity and how blocking vs non blocking works.

This simple example above can be done using Indy as is by selecting before 
hand too.
