Well, this is embarrassing. It turns out RedHat has this documented in their RHEL series, but not in Fedora. It's also not in the man-pages project. The attached patch has a better explanation of the option than the one I submitted earlier today. This text comes from RedHat. On 09/11/2012 02:35 PM, Todd Lewis sent:
The attached "diff -u" formatted patch applies to http://git.kernel.org/?p=docs/man-pages/man-pages.git;a=blob_plain;f=man5/resolv.conf.5;hb=HEAD as it existed on 2012-09-11--14:31. It adds documentation for the "single-request-reopen" option. This information was found in the changelog notes (http://sourceware.org/ml/libc-alpha/2009-10/msg00063.html) from Ulrich Drepper. The issue and solution were both brought to my attention by a discussion on our internal mailing list which mentioned this undocumented feature. Several users indicated they have been suffering from slow DNS resolutions on machines behind certain firewalls and that this solved their problems. Seems like others would like to know about it.
