Pardon a bit of apparently bad news. I also posted this to
ruby-talk/comp.lang.ruby.
This looks as bad as the CGI DOS a couple months back for anyone running
WEBrick as an actual public server, and not just during rails
development and testing.

Collaborating a bit with ruby-talk guys on a SafeReader gem that might
address this, but don't imagine you want to wait for that nor incur the
overhead for now until we can get a C extension version finished.
If I've overlooked something, please let me know. Thanks.
