Hm, I'm surprised the tests failed again for you then. Both of the 
patches I posted to fix the tests set the 'server-name' to a (hopefully) 
unique value.

Still, I think it's a good idea to use a temporary directory to hold the 
server file, so here's a patch that does that. I've tried this patch 
with a production Emacs server running at the same time in several 
different configurations (with 'server-use-tcp' on and off, and with 
--daemon), and the tests all pass locally for me on GNU/Linux.
