Re: Unexpected async behaviour?

It's not a bug, it's a feature :) You probably missed 
[this](https://nim-lang.github.io/Nim/manual.html#closures-creating-closures-in-loops)
 part of the manual where it is explained that closures capture variable by 
reference. In your example the inner `serve` captures `c` by reference and, as 
a result, you're always listening on the last accepted connection. To solve 
this problem you can just create a local copy of `c` and use it.
