 Same as moonbridge_io.tcpconnect(hostname, port), except that this function
 does not block and immediately returns a socket object.
 
+Note: The current implementation still blocks during the DNS lookup. Use a
+numeric IP address as hostname to be truly nonblocking.
+
 In case of an I/O error, nil (as first return value) plus an error message (as
 second result value) may be returned. However, connection errors may also be
 reported on first read or write on the socket.
