I'm doing literally what the warning message says to do -- i.e. setting 
the content-length of the response -- but I'm still getting the warning.

We were seeing this as well when using webrick with Rails. However, 
putting

gem 'webrick', '= 1.3.1'

in the Gemfile seemed to fix it, which is strange, since the standard 
library one is also v1.3.1.  Is it possible that the gem is different 
than stdlib?

I cannot reproduce it with the example code given or by removing 
(({response.body = ''})), (({response.content_length = 0})) or both 
lines with latest trunk.
