Hi.
I'm not really sure how to get your test case to work. I try it in
vanilla Ruby, and it hangs on the s.read(10)-line. (which it should,
since we have not sent something to google http to elicit an answer)
I guess the real question is: how do you get to the "Still haven't
crashed"-line at all?
Regards
Ola Bini
