Unfortunately that won't work at the moment. The underlying implementation of recv is nonblocking. A blocking Windows recv call is noninterruptible, unfortunately (at least up to Windows 2003), so this was necessary to handle signals or thread-cancellation. Due to its nonblocking nature under the hood, this doesn't support SO_RCVTIMEO and SO_SNDTIMEO and, surprisingly, we never had a complaint about that, despite its age. I can't promise a quick solution, but I put implementing handling of SO_RCVTIMEO and SO_SNDTIMEO in recv/send on my TODO list. Of course, patches are welcome, too. For the time being, I suggest to use select or poll with timeout instead.
