Ok, good. It was almost certainly the select/poll race fix - Mariusz
Ceier reported a problem with youtube hanging, and confirmed that the
poll/select fix seems to have cleared that one up. I suspect that your
hang on fb and spiegel.de were the same thing.

So I think the pipe code is stable again with current -git. Thanks for
reporting and testing,
