Can I alternate between server and client using an ESP8266Wifi for the networking device?

On the ESP8266 WIFI MODULE page at http://www.espruino.com/ESP8266 under the heading GOTCHAS, it is very clear

You can only have one TCP/IP server, and while it is active you can not have any clients

In my mind this hinges on the word "active".

So I've used http://www.espruino.com/Reference#t_l_httpSrv_close to close a running http server and can then do a client require("http").get(...) successfully.
However, when I try to restart the server using another http://www.espruino.com/Reference#t_l_httpSrv_listen
I get the following error:
```
Uncaught Error: CIPSERVER failed (no change)  at line 2 col 20
(a?a:"Timeout")+")");
                       ^ 
in function called from system
```
Is there a way to restart the server or do I need to "createServer" again: seems wasteful?
