Does anyone ever see alot of errors like this:  
Exception `Net::HTTPBadResponse’ at /usr/lib/ruby/1.8/net/http.rb:2022

- wrong status line: _SOME HTML CODE HERE_

When using threads and mechanize? I’m relatively certain that this is  
some bad behavior between threads and the net/http library, but does  
anyone have any advice as far as the upper limit of threads you want  
to run at once when using mechanize/nethttp?
