Is nginx vulnerable to the Hash Table Vulnerability (n.runs AG)?

Without going through the way nginx parses an incoming request, I'm unsure
if nginx isn't vulnerable to this, because of the availability to grab the
value of a GET parameter via
http://wiki.nginx.org/HttpCoreModule#.24arg_PARAMETER. My hope is that
especially if an $arg_PARAMETER isn't used in the config, it is not
vulnerable because it wouldn't even attempt to parse the parameters, but I
can't be sure.

Can anyone speak to this?
