Bug #96080 for Apache2-AuthenNTLM: Unstable behavior under some stress

Apache2-AuthenNTLM-0.02 $ perl -v This is perl, v5.10.1 (*) built for x86_64-linux-thread-multi Copyright 1987-2009, Larry Wall Perl may be copied only under the terms of either the Artistic License or the GNU General Public License, which may be found in the Perl 5 source kit.

Restarting Apache2 allows operations to continue. There's a suggestion made here: https://drupal.org/node/44718#comment-3153084 on how to fix the issue, and it seems to work well. The corresponding patch is attached.
