Nim 1.6 vs 2 (1.9) Working with channels

[gs]

This seems to be the fixed version... How should we know what was wrong in the 
other one?

But two things... You use spawn, while the docs say

> Note: Channels are designed for the Thread type. They are unstable when used 
> with spawn

<https://nim-lang.org/docs/channels_builtin.html>

changed for 2.0 ?

And just to be sure you removed something like this when you removed the close?
    
    
    of "d":
          if not isDownload and not isFetch:
            #openChannels() # This one?
            spawn fetchStream(Url)
            spawn downloadStream(Url)
    
    
    Run
