Thanks.
That helps but I'm now getting really strange results.
I've searched high and low and can't find an example that does what I want;
most are older and show how to disable tcp, not enable it with good results.

.xserverrc:
  /usr/local/bin/X :0 -listen tcp
or
  /usr/local/bin/X :0 -listen local -listen tcp

1. When using either of the above, the server and apps take a lot longer to
   start and settle down to the initial display.
2. My startx starts up a clock, xfwm4, and 5 xterms; the last xterm is the 
   controlling terminal.
   When exiting the controlling xterm, I'm left with a set of xterms instead of
   returning to a normal system prompt without X.  It's as if the server used 
   two screens, one behind the other.  Exiting the controlling terminal again 
   (the one left on the display after the first exit) leaves the display in a 
   mode where I can't see anything, and I have to power off and restart.

What I want it to do is start up normally using the standard unix sockets, 
but allow logins over tcp.  Obviously I'm doing something wrong, but the docs
aren't very clear as I read them.
