It actually will throw on Windows and can be tricked into it on 
Linux; it is an operating system thing more than a language thing.

The best way to do that is to separate the server modules into 
independent processes. Then if one crashes, the others keep 
running without fear of corruption.

So instead of server modules, try doing mini servers that 
communicate with the main server. This is how a lot of newer 
programs are written because of the reliability and security 
benefits it offers.
