Yes, "echo hello; bash -i" tells us that only ssh connection was 
established.
It makes race condition a bit less noticeable and in 70% it connects 
successfully,
but in other 30% we still get connection refused. So, yeah, there is no 
other way
to check if ssh tunnel is ready than to try to connect to it.
