Here requests take place in the program, rather than going through nscd.
I just tried (with glibc 2.17) and indeed, I get EAI_SYSTEM when nscd is
*not* running, and EAI_NONAME when nscd is running.
I believe the former is a bug, and I reported it at
<http://sourceware.org/bugzilla/show_bug.cgi?id=15635>. Let’s see...
Thanks!
