Unix Sockets can't receive messages or I'm not using them properly

[trtt]

Hi,

I've this code:
    
    
    import net
    
    let socket = newSocket(AF_UNIX, SOCK_STREAM, IPPROTO_IP)
    socket.connectUnix("...")
    
    #socket.send("...") - this works every time
    
    var data: string = newStringOfCap(1024)
    let rd = socket.recv(data, 1024, 1000) # this one always fails
    echo $rd
    
    socket.close()
    
    
    Run

I'm writing a neovim client in nim and I can send any message, see it getting 
processed in the neovim logs and I also see their effects - but I can only 
receive negative responses for some reason. Other neovim clients do the _exact_ 
same thing and they work through unix sockets fine(this is not my first neovim 
client). The hasDataBuffered() also reports false every time. What's missing? 
Any idea?
