The problem is AFTER the fork. CoreFoundation means any use of Cocoa
GUI stuff.

If run with --daemon now, it returns "t". If run emacs -Q then
"server-start" it returns "nil".
server-name is "server" in both cases.
Here's some more info. If I do 'lsof | grep <process ID>', when
running --daemon, I get:
Emacs 6608 arobert 3u unix 0x11bf3110 0t0 /
tmp/emacs503/server
whereas when running normal+server-start I get:
Emacs 6600 arobert 6u unix 0x11bf3110 0t0 /
var/folders/90/90K8geLYFgW7CC5i5eRKmk+++TQ/-Tmp-/emacs503/server
Does this tell anything? I'm not too knowledgeable about sockets, but
the second one looks more "official".
