> send connect three sockets and read from each of the asynchronously?
like this?

> Issue I'm seeming to have is timeout never occurs upon false connections
Try to wrap with connection future
[withTimeout](https://nim-lang.github.io/Nim/asyncdispatch.html#withTimeout%2CFuture%5BT%5D%2Cint)
like
let
conn1 = sock0.connect(host, Port 22).withTimeout(1000)
conn2 = sock1.connect(host, Port 22).withTimeout(1000)
conn3 = sock2.connect(host, Port 22).withTimeout(1000)
if not await(conn1) or not await(conn2) or not await(conn3):
echo "timeout reached in any connection"
Run
