There are some 'sleep 1' commands between starting the socat server and its corresponding client to avoid races due to the server not being ready as we start sending data. However, those don't cover all the cases where we might need them, and in some cases the sleep command actually ended up being before the server even starts. This fixes occasional failures in TCP and UDP simple transfer tests, that became apparent with the new command dispatch mechanism.
